Twisted Conjugacy Growth of the Generalised Heisenberg Groups
We determine the twisted conjugacy growth function for automorphisms on generalised Heisenberg groups. In particular we demonstrate for these groups that up to a natural equivalence this function is either given by $n^k$ or $n^k\ln(n)$ for some constant $k$. We give a precise description for which of these functions we obtain in terms of dimensions and ranks on the upper and lower central series. In particular we obtain that the twisted conjugacy growth is always bounded by the conjugacy growth.

Quantitative growth of multi-recurrence sequences
In 1982, Schlickewei and Van der Poorten claimed that any multi-recurrence sequence has, essentially, maximal possible growth rate. Fourty years later, Fuchs and Heintze provided a non-effective proof of this statement. In this paper, we prove a quantitative version of that result by giving an explicit upper bound for the maximal possible growth rate of a multi-recurrence. Moreover, we also give a function field analogue of the result, answering a question posed by Fuchs and Heintze when provin…

Reciprocity of Magnetism and Nanostructure Growth
The growth of thin films and nanostructures is a fundamental process for constructing both model-type systems and nanoscale devices, where performance and functionalities can be controlled by the choice of parameters. For magnetic systems the crystal structure, material composition, size, and shape determine already most of the magnetism-related properties. Here, we investigate the reciprocal route, which is controlling nanostructure growth via magnetism. To this end we deposit Co on a uniaxial…

Supermassive black hole growth from stellar binary encounters
The growth of supermassive black holes (SMBHs) remains a central problem in astrophysics, with current observations providing only limited constraints on the underlying mechanisms. One possible growth channel is stellar accretion via the Hill's mechanism, wherein a SMBH tidally breaks up a passing binary star, capturing and eventually accreting a member of the binary. We adopt a model to predict capture rates from parameters that include the central number density of stars, the stellar velocity…

Examples of stable-like random walks on groups of polynomial growth
We consider several families of long jump random walks on groups of polynomial volume growth which are naturally expected to have a stable-like behavior. We then prove optimal pseudo-Poincaré inequalities for these walks. These pseudo-Poincaré inequalities allow us to show that the random walks in questions indeed have a stable-like behavior and to obtain detailed estimates.

We then analyze this quantity in two complementary ways, revealing universal dynamical behavior. First, we develop a heuristic picture for generic Floquet systems that connects Loschmidt echoes, out-of-time-order correlator…

Uniqueness of the asymptotic limits for Ricci-flat manifolds with linear volume growth
Under natural assumptions on curvature and cross section, we establish the uniqueness of asymptotic limits and the exponential convergence rate for complete noncollapsed Ricci-flat manifolds with linear volume growth, which are known to only admit cylindrical asymptotic limits. In dimension four, these assumptions hold automatically, yielding unconditional uniqueness and convergence. In particular, our results show that all asymptotically cylindrical Calabi--Yau manifolds converge exponentially…

However, due to the exponential growth of game trees, many games remain unsolved, even though methods like AlphaZero have demonstrated super-human level in game playing.

We show that for a wide range of integrands, including the least gradient problem and the non-parametric Plateau problem, and under suitable mean-convexity conditions of the boundary, minimizers of the relaxed problem attain the boundary data in the trace sense if it lies in $BV$ or $W^{α,p}$ with $αp\geq 2$ witho…

This paper introduces a flexible hybrid longitudinal modeling that integrates features of the Actor-Partner Interdependence Model (APIM) and the Common Fate Growth Model (CFGM) to simultaneously estimate individual-level and shared dyad-level effects.

Towards Intelligent Battery Management via A Five-Tier Digital Twin Framework
Battery management systems (BMSs) are critical to ensuring safety, efficiency, and longevity across electronics, transportation, and energy storage. However, with the rapid growth of lithium-ion batteries, conventional reactive BMS approaches face limitations in health prediction and advanced maintenance management, resulting in increased safety risks and economic costs. To address these challenges, we propose a five-tier digital twin framework for intelligent battery management. The framework …

Black Hole Entropy and Complexity Growth in Horndeski Gravity within the AdS/BCFT Framework
This work investigates the connection between quantum complexity and gravitational dynamics within the framework of Horndeski gravity, extending the AdS/BCFT correspondence to include scalar-tensor interactions. By refining the ``\(complexity = action\)'' conjecture we investigate how Horndeski gravity modifies the Wheeler-DeWitt patch and the causal structure of the black hole. Our analysis reveals that the linear growth of complexity, proportional to the product of black hole entropy and temp…

"""
Traditional politics of assistance and the repression of unemployment were now called into question. The need for reform became urgent.
Poverty was gradually separated from the old moral confusions. Economic crises had shown that unemployment could not be confused with indolence, as indigence and enforced idleness spread throughout the countryside, to precisely the places that had previously been considered home to the purest and most immediate forms of moral life. This demonstrated that poverty did not solely fall under the order of the fault: ‘Begging is the fruit of poverty, which in turn is the consequence of accidents in the production of the earth or in the output of factories, of a rise in the price of basic foodstuffs, or of growth of the population, etc.’ Indigence became a matter of economics.
But it was not contingent, nor was it destined to be suppressed forever. There would always be a certain quantity of poverty that could never be effaced, a sort of fatal indigence that would accompany all forms of society until the end of time, even in places where all the idle were employed: ‘The only paupers in a well governed state must be those born in indigence, or those who fall into it by accident.’ This backdrop of poverty was somehow inalienable: whether by birth or accident, it formed an inevitable part of society. The state of lack was so firmly entrenched in the destiny of man and the structure of society that for a long time the idea of a state without paupers remained inconceivable: in the thought of philosophers, property, work and indigence were terms linked right up until the nineteenth century.
This portion of poverty was necessary because it could not be suppressed; but it was equally necessary in that it made wealth possible. Because they worked but consumed little, a class of people in need allowed a nation to become rich, to release the value of its fields, colonies and mines, making products that could be sold throughout the world. An impoverished people, in short, was a people that had no poor. Indigence became an indispensable element in the state. It hid the secret but most real life of society. The poor were the seat and the glory of nations. And their noble misery, for which there was no cure, was to be exalted:
«My intention is solely to invite the authorities to turn part of their vigilant attention to considering the portion of the People who suffer … the assistance that we owe them is linked to the honour and prosperity of the Empire, of which the Poor are the firmest bulwark, for no sovereign can maintain and extend his domain without favouring the population, and cultivating the Land, Commerce and the Arts; and the Poor are the necessary agents for the great powers that reveal the true force of a People.»
What we see here is a moral rehabilitation of the figure of the Pauper, bringing about the fundamental economic and social reintegration of his person. Paupers had no place in a mercantilist economy, as they were neither producers nor consumers, and they were idle, vagabond or unemployed, deserving nothing better than confinement, a measure that extracted and exiled them from society. But with the arrival of the industrial economy and its thirst for manpower, paupers were once again a part of the body of the nation.

Quadratic Growth Model with Discontinuity: A Link between Monostable and Bistable Traveling Waves
We classify traveling waves and stationary solutions of a reaction-diffusion equation arising in population dynamics with Allee-type effects. The reaction term is given by a quadratic polynomial with a discontinuity at zero, which captures finite-time extinction for sub-threshold populations. This discontinuity induces a free boundary in the wave profile, a phenomenon that distinguishes the model from the classical logistic or Allen-Cahn equations. A complete scenario is presented that connects…

Hierarchical assembly impedes the inference of stellar mass growth histories for individual galaxies
Some massive, quiescent galaxies at z>3 appear to contain considerable numbers of old stars (forming at z>7). Works inferring the star formation histories of at least one such galaxy observed with JWST have suggested that the assembly of so much stellar mass so early may challenge the well-established Cold Dark Matter (CDM) cosmological framework, or else indicate extraordinarily high past star formation efficiencies. However, these studies implicitly assume that all the stars in place at the e…

Dark-to-black super accretion as a mechanism for early supermassive black hole growth
The discovery of supermassive black holes with masses $\gtrsim 10^9 M_\odot$ at redshifts $z\gtrsim 10$ challenges conventional formation scenarios based on baryonic accretion and mergers within the first few hundred million years. We propose an alternative channel in which ultralight scalar dark matter undergoes dark-to-black conversion via quasi-bound state depletion around black hole seeds. We estimate the accretion rate of the scalar field as a function of the boson mass parameter $μ$ and …

Exponential convergence of a distributed divide-and-conquer algorithm for constrained convex optimization on networks
We propose a divide-and-conquer (DAC) algorithm for constrained convex optimization over networks, where the global objective is the sum of local objectives attached to individual agents. The algorithm is fully distributed: each iteration solves local subproblems around selected fusion centers and coordinates only with neighboring fusion centers. Under standard assumptions of smoothness, strong convexity, and locality on the objective function, together with polynomial growth conditions on the …

In this work, we define optimal e-values for testing between maximum entropy models, both in the microcanonical (hard constraints) and canonical (soft constraints) settings. We show that, when testing between two hypotheses that are both microcanonical, the so-called growth-rate optimal …

The adaptive EM schemes for McKean-Vlasov SDEs with common noise in finite and infinite horizons
This paper is dedicated to investigating the adaptive Euler-Maruyama (EM) schemes for the approximation of McKean-Vlasov stochastic differential equations (SDEs) with common noise. When the drift and diffusion coefficients both satisfy the superlinear growth conditions, the $L^p$ convergence rates in finite and infinite horizons are revealed, which reacts to the particle number and step size. Subsequently, there is an illustration of the theory results by means of two numerical examples.

On the stability of Ricci flow on hyperbolic 3-manifolds of finite volume
On a hyperbolic 3-manifold of finite volume, we prove that if the initial metric is sufficiently close to the hyperbolic metric $h_0$, then the normalized Ricci-DeTurck flow exists for all time and converges exponentially fast to $h_0$ in a weighted Hölder norm. A key ingredient of our approach is the application of interpolation theory. Furthermore, this result is a valuable tool for investigating minimal surface entropy, which quantifies the growth rate of the number of closed minimal surf…
