Good Morning #Canada
In August 1998, the Supreme Court of Canada ruled that Quebec could not legally secede from Canada unilaterally. The court's decision affirmed that any secession would require a constitutional amendment negotiated with the federal government and other provinces. This ruling stemmed from a reference case initiated by the federal government following a close referendum on Quebec sovereignty in 1995. Although Quebec was represented at the Supreme Supreme Court hearing, they did not participate in presenting arguments. They essentially ignored the ruling and planned a future referendum, which never happened.
This ruling established an important precedent that Alberta separatists should pay attention to. But details such as this ruling, aboriginal rights, or common sense seem to escape their attention spans.

Bell Inequality Violations Without Entanglement? It's Just Postselection
Recently Wang et al. have reported a violation of a Bell inequality without entanglement [arXiv:2507.07756]. We show that their result is an artifact of postselection. It is well known that postselection may yield Bell inequality violations, both in classical toy models and in real experiments with delayed-choice entanglement-swapping. Here we describe a classical analog of Wang et al.'s experiment, and show that it produces essentially the same results as their quantum version. We explain in d…

Data-driven optimized high-order WENO schemes with low-dissipation and low-dispersion
Classical high-order weighted essentially non-oscillatory (WENO) schemes are designed to achieve optimal convergence order for smooth solutions and to maintain non-oscillatory behaviors for discontinuities. However, their spectral properties are not optimal, which limits the ability to capture high-frequency waves and small-scale features. In this paper, we propose a data-driven optimized method to improve the spectral properties of the WENO schemes. By analyzing the approximate dispersion rela…

Each of them gives rise to a distance-regular graph on a vertex set $X$, naturally endowed with the path metric. We study $d$-codes in these …

When the semi-classical parameter $\hbar \in (0,1]$ is fixed, our result is essentially covered by the recent work by Nguyen and You [arXiv:2408.15860]; however, the novelty of this paper is the uniformity with respect to $\hbar$.

Maximal sets of a given diameter in Hamming cubes
A subset of the Hamming cube over $n$-letter alphabet is said to be $d$-maximal if its diameter is $d$, and adding any point increases the diameter. Our main result shows that each $d$-maximal set is either of size at most $(n+o(n))^d$ or contains a non-trivial Hamming ball. The bound of $(n+o(n))^d$ is asymptotically tight. Additionally, we give a non-trivial lower bound on the size of any $d$-maximal set and show that the number of essentially different $d$-maximal sets is finite.

Optimal Hamilton-type gradient estimates for the heat equation on noncompact manifolds
We derive localized and global noncompact versions of Hamilton's gradient estimate for positive solutions to the heat equation on Riemannian manifolds with Ricci curvature bounded below. Our estimates are essentially optimal and significantly improve on all previous estimates of this type. As applications, we derive a new and sharp, space only, local pseudo-Harnack inequality, as well as estimates of the spatial modulus of continuity of solutions.

Material Fingerprinting: A shortcut to material model discovery without solving optimization problems
We propose Material Fingerprinting, a new method for the rapid discovery of mechanical material models from direct or indirect data that avoids solving potentially non-convex optimization problems. The core assumption of Material Fingerprinting is that each material exhibits a unique response when subjected to a standardized experimental setup. We can interpret this response as the material's fingerprint, essentially a unique identifier that encodes all pertinent information about the material'…

When are two algorithms the same? Towards addressing Hilbert's 24th problem
The informal question of when two theorem proofs are "essentially the same" goes back to David Hilbert, who considered adding it (or something largely equivalent) to his famous list of open problems, but eventually decided to leave it out. Given that the notion of a formal proof is closely related to that of a (computer) program, i.e. a recursive function, it may be useful to ask the same question with regard to programs instead. Here we propose a minimalistic approach to this question within R…

The Parameter Report: An Orientation Guide for Data-Driven Parameterization
A strength of parameterized algorithmics is that each problem can be parameterized by an essentially inexhaustible set of parameters. Usually, the choice of the considered parameter is informed by the theoretical relations between parameters with the general goal of achieving FPT-algorithms for smaller and smaller parameters. However, the FPT-algorithms for smaller parameters usually have higher running times and it is unclear whether the decrease in the parameter value or the increase in the r…

Explainable Knowledge Graph Retrieval-Augmented Generation (KG-RAG) with KG-SMILE
Generative AI, such as Large Language Models (LLMs), has achieved impressive progress but still produces hallucinations and unverifiable claims, limiting reliability in sensitive domains.

However, RAG remains opaque and essentially a black box, heavily dependent on data quality. We developed a method-agnostic, perturbation-based fram…

Structural and rigidity properties of Lie skew braces
We investigate structural and rigidity properties of \emph{Lie skew braces} (LSBs), objects essentially known in the literature as \emph{post--Lie groups}, obtained by endowing a manifold with two compatible group laws that share the same identity element. LSBs extend skew left braces, which are central to the study of non-involutive set-theoretic solutions of the Yang--Baxter equation, to the smooth category. Our first main result shows that, for every connected LSB $(G,\cdot,\circ)$, linearit…

Modelling Program Spaces in Program Synthesis with Constraints
A core challenge in program synthesis is taming the large space of possible programs. Since program synthesis is essentially a combinatorial search, the community has sought to leverage powerful combinatorial constraint solvers. Here, constraints are used to express the program semantics, but not as a potentially potent tool to remove unwanted programs. Recent inductive logic programming approaches introduce constraints on the program's syntax to be synthesized. These syntactic constraints allo…

Understanding topological dynamics of hyperbolic dynamical systems via examples
Topological dynamics constitutes the study of asymptotic properties of orbits under flows or maps on the Hausdorff phase space. Hyperbolic dynamics is the study of differentiable flows or maps that are usually characterized by the presence of expanding and contracting directions for the associated derivative on some manifold. We study some topological dynamics, essentially the property of `proximality', of two prototype examples of hyperbolic dynamical systems - \emph{Arnold's Cat Map} and \emp…

IR Spectroscopic Studies of Gas-Phase Peptides
Proteins are vital biological molecules found in every living organism, and their function is determined by what shape they fold into. Peptides are essentially subsets of proteins, and therefore ideal as model systems for protein folding. The structure of a molecule is closely related to its vibrational absorption spectrum, which lies in the infrared (IR) range. However, in vivo IR spectroscopy is hindered by interference from the surrounding water. Therefore, peptides are preferably studied is…

Two improvements upon the paper "Wiener--Luxemburg amalgam spaces"
This short note seeks to present two new results that essentially improve the corresponding statements from the author's paper ``Wiener--Luxemburg amalgam spaces''. Specifically, in our first result, we show that when both the local and the global components of a pair of r.i. quasi-Banach function spaces are appropriately ordered, then both their sum and intersection can be characterised as the appropriate amalgam of said spaces, up to equivalence of quasinorms. Then, in our second result, we p…

Brownian motion on the Fubini extension space and applications
The aim of this paper is to establish a certain equivalence between a Brownian motion on a Fubini extension space and a collection of essentially pairwise independent Brownian motions on the marginal sample spaces. This equivalence allows us to state a Girsanov theorem that preserves pairwise independence and to formulate graphon stochastic differential equations as a single McKean-Vlasov type equation driven by a standard Brownian motion.

From objects finitely presented by a rigid object in a triangulated category to 2-term complexes
For a rigid object $M$ in an algebraic triangulated category $\ct$, a functor $\fpr(M)\to\ch^{[-1,0]}(\proj A)$ is constructed, which essentially takes an object to its `presentation', where $\fpr(M)$ is the full subcategory of $\ct$ of objects finitely presented by $M$, $A$ is the endomorphism algebra of $M$ and $\ch^{[-1,0]}(\proj A)$ is the homotopy category of complexes of finitely projective $A$-modules concentrated in degrees $-1$ and $0$. This functor is shown to be full and dense and it…

Applications of decision diagrams in quantum circuit analysis have been an active research area. Our work introduces FeynmanDD, a new method utilizing standard and multi-terminal decision diagrams for quantum circuit simulation and equivalence checking.

Interpolation with Automated First-Order Reasoning
We consider interpolation from the viewpoint of fully automated theorem proving in first-order logic as a general core technique for mechanized knowledge processing. For Craig interpolation, our focus is on the two-stage approach, where first an essentially propositional ground interpolant is calculated that is then lifted to a quantified first-order formula. We discuss two possibilities to obtain a ground interpolant from a proof, with clausal tableaux, and with resolution. Established preproc…

Conservative approximation-based feedforward neural network for WENO schemes
In this work, we present the feedforward neural network based on the conservative approximation to the derivative from point values, for the weighted essentially non-oscillatory (WENO) schemes in solving hyperbolic conservation laws. The feedforward neural network, whose inputs are point values from the three-point stencil and outputs are two nonlinear weights, takes the place of the classical WENO weighting procedure. For the training phase, we employ the supervised learning and create a new l…

On graphs, homology bases, and triangulated homology spheres
We describe a construction that takes as input a graph and a basis for its first homology, and returns a triangulation of a 3-dimensional homology sphere. This makes precise an idea of M. Gromov and A. Nabutovski. The immediate application, essentially described by Gromov, is to translate problems about asymptotics of homology sphere triangulations to asymptotic counting problems for constant-degree graphs with "short" homology bases. We construct families of 3- sphere triangulations with dual …
