"I have worked pretty extensively with all three of cabal, stack and Nix throughout my career and my intuition based on that experience is that the only improvement to the Haskell command-line experience that is viable and that will “win” in the long run is one that is directly upstreamed into cabal.

On the set partitions that require maximum sorts through the $aba-$avoiding stack
Recently, Xia introduced a deterministic variation $ϕ_σ$ of Defant and Kravitz's stack-sorting maps for set partitions and showed that any set partition $p$ is sorted by $ϕ^{N(p)}_{aba}$, where $N(p)$ is the number of distinct alphabets in $p$. Xia then asked which set partitions $p$ are not sorted by $ϕ_{aba}^{N(p)-1}$. In this note, we prove that the minimal length of a set partition $p$ that is not sorted by $ϕ_{aba}^{N(p)-1}$ is $2N(p)$. Then we show that there is only one set partitio…

The stack number of a directed acyclic graph $G$ is the minimum $k$ for which there is a topological ordering of $G$ and a $k$-coloring of the edges such that no two edges of the same color cross, i.e., have alternating endpoints along the topological ordering.

Non-semisimple Crane-Yetter theory varying over the character stack
Patrick Kinnear
https://arxiv.org/abs/2404.19667 https://arxiv.org/pdf/2404.19667
arXiv:2404.19667v1 Announce Type: new
Abstract: We construct a relative version of the Crane-Yetter topological quantum field theory in four dimensions, from non-semisimple data. Our theory is defined relative to the classical $G$-gauge theory in five dimensions -- this latter theory assigns to each manifold $M$ the appropriate linearization of the moduli stack of $G$-local systems, called the character stack. Our main result is to establish a relative invertibility property for our construction. This invertibility echoes -- recovers and greatly generalizes -- the key invertibility property of the original Crane-Yetter theory which allowed it to capture the framing anomaly of the celebrated Witten-Reshetikhin-Turaev theory. In particular our invertibilty statement at the level of surfaces implies a categorical, stacky version of the unicity theorem for skein algebras; at the level of 3-manifolds it equips the character stack with a canonical line bundle. Regarded as a topological symmetry defect of classical gauge theory, our work establishes invertibility of this defect by a gauging procedure.

"By 1973, the first volume of the defining work of our craft, “The Art of Computer Programming” had been available in bookstores since 1968, and its first chapter literally consisted of a 100-something page long introduction to various mathematical concepts. Induction, logarithms, series, matrices, elementary number theory, permutations and factorials, Fibonacci numbers, are some of the subjects exposed in those beautifully typeset pages."

How much math knowledge does a programmer need to know to fulfill their job?

The Order of the (123, 132)-Avoiding Stack Sort
Let $s$ be West's deterministic stack-sorting map. A well-known result (West) is that any length $n$ permutation can be sorted with $n-1$ iterations of $s.$ In 2020, Defant introduced the notion of highly-sorted permutations -- permutations in $s^t(S_n)$ for $t \lessapprox n-1.$ In 2023, Choi and Choi extended this notion to generalized stack-sorting maps $s_σ,$ where we relax the condition of becoming sorted to the analogous condition of becoming periodic with respect to $s_σ.$ In this work,…

One Stack to Rule them All: To Drive Automated Vehicles, and Reach for the 4th level
Most automated driving functions are designed for a specific task or vehicle. Most often, the underlying architecture is fixed to specific algorithms to increase performance. Therefore, it is not possible to deploy new modules and algorithms easily. In this paper, we present our automated driving stack which combines both scalability and adaptability. Due to the modular design, our stack allows for a fast integration and testing of novel and state-of-the-art research approaches. Furthermore, it…

Design, Fabrication, and Assembly of the SPARC Toroidal Field Model Coil
The SPARC Toroidal Field Model Coil (TFMC) is the first large-scale (∼3 m), high-field (∼20 T) superconducting fusion magnet based on Rare Earth Yttrium Barium Copper Oxide (REBCO). Weighing 10,058 kg and utilizing 270 km of REBCO, the TFMC is a non-insulated, stack-in-plate style superconducting magnet. It has three main components: (1) the winding pack; (2) the structural case; and (3) the case extensions, or plena. The winding pack is composed of sixteen single pancakes with two terminat…

On products of K-moduli spaces
We study the K-moduli space of products of Fano varieties in relation to the product of K-moduli spaces of the product components. We show that there exists a well-defined morphism from the product of K-moduli stacks of Fano varieties to the K-moduli stack of their product. We further show that this morphism is an isomorphism if the two varieties are non-isomorphic, and a torsor if they are. Our results rely on the theory of stacks, and we extend them to general Artin stacks admitting good modu…

R5Detect: Detecting Control-Flow Attacks from Standard RISC-V Enclaves
Embedded and Internet-of-Things (IoT) devices are ubiquitous today, and the uprising of several botnets based on them (e.g., Mirai, Ripple20) raises issues about the security of such devices. Especially low-power devices often lack support for modern system security measures, such as stack integrity, Non-eXecutable bits or strong cryptography. In this work, we present R5Detect, a security monitoring software that detects and prevents control-flow attacks on unmodified RISC-V standard architec…

On the stack of 0-dimensional coherent sheaves: structural aspects
Let $X$ be a quasiprojective scheme. In this expository note we collect a series of useful structural results on the stack $\mathscr{C}oh^n(X)$ parametrising $0$-dimensional coherent sheaves of length $n$ over $X$. For instance, we discuss its functoriality (in particular its behaviour along étale maps), the support morphism to $\mathrm{Sym}^n(X)$, and its relationship with the Quot scheme of points $\mathrm{Quot}_X(\mathcal E,n)$ for fixed $\mathcal E\in \mathrm{Coh}(X)$.

$\textbf{Splat-MOVER}$: Multi-Stage, Open-Vocabulary Robotic Manipulation via Editable Gaussian Splatting
We present Splat-MOVER, a modular robotics stack for open-vocabulary robotic manipulation, which leverages the editability of Gaussian Splatting (GSplat) scene representations to enable multi-stage manipulation tasks. Splat-MOVER consists of: (i) $\textit{ASK-Splat}$, a GSplat representation that distills latent codes for language semantics and grasp affordance into the 3D scene. ASK-Splat enables geometric, semantic, and affordance understanding of 3D scenes, which is critical for many robotic…

Galois descent for motivic theories
We give necessary conditions for a category fibred in pseudo-abelian additive categories over the classifying topos of a profinite group to be a stack; these conditions are sufficient when the coefficients are $\mathbf{Q}$-linear. This applies to pure motives over a field in the sense of Grothendieck, Deligne-Milne and André, to mixed motives in the sense of Nori and to several motivic categories considered in arXiv:1506.08386 [math.AG]. We also give a simple proof of the exactness of a sequen…

Nonabelian Hodge theory for stacks and a stacky P=W conjecture
We introduce a version of the P=W conjecture relating the Borel-Moore homology of the stack of representations of the fundamental group of a genus g Riemann surface with the Borel-Moore homology of the stack of degree zero semistable Higgs bundles on a smooth projective complex curve of genus $g$. In order to state the conjecture we propose a construction of a canonical isomorphism between these Borel-Moore homology groups. We relate the stacky P=W conjecture with the original P=W conjecture co…

How Do OSS Developers Utilize Architectural Solutions from Q&A Sites: An Empirical Study
Developers utilize programming-related knowledge (e.g., code snippets) on Q&A sites (e.g., Stack Overflow) that functionally matches the programming problems they encounter in their development. Despite extensive research on Q&A sites, being a high-level and important type of development-related knowledge, architectural solutions (e.g., architecture tactics) and their utilization are rarely explored. To fill this gap, we conducted a mixed-methods study that includes a mining study and a survey …

Rational motives on pro-algebraic stacks
We define an $\infty$-category of rational motives for cofiltered limits of algebraic stacks, so-called pro-algebraic stacks. We show that it admits a $6$-functor formalism for certain classes of morphisms. We deal with three examples that are included in this formalism. The stack of Barsotti-Tate groups, seen as a pro-algebraic stack via its truncations, the base change of an algebraic stack $X$ over a field $k$ to a Galois extension $L$, and a pro-algebraic stack related to Edidin-Graham's co…
