Analyzing the Free States of one Quantum Resource Theory as Resource States of Another

Advanced Quantum Technologies, Volume 9, Issue 2, February 2026.
The article investigates how free states in one quantum resource theory can become highly resourceful in another. It systematically studies multipartite entanglement, fermionic non‐Gaussianity, imaginarity, realness, spin coherence, Clifford non‐stabilizerness, Sn‐equivariance, and non‐uniform entanglement, combining rigorous analytical tools and ...

Complete verification of strong BSD for many modular abelian surfaces over ${\mathbf {Q}}$

Forum of Mathematics, Sigma
We develop the theory and algorithms necessary to be able to verify the strong Birch–Swinnerton-Dyer Conjecture for absolutely simple modular abelian varieties over ${\mathbf {Q}}$ . We apply our methods to all 28 Atkin–Lehner quotients of $X_0(

Topological Polar Textures in van der Waals Moiré Superlattices

Small Structures, Volume 7, Issue 2, February 2026.
Moiré superlattices allow the realization of several novel properties, including the formation of complex topological polarization textures in ultrathin samples consisting of layered 2D materials. This review highlights the rapid progress in this emerging field, both through theory and experiment, discusses the field's potential implications, and draws

Equivariant Kuznetsov components for cubic fourfolds with a symplectic involution

Bulletin of the London Mathematical Society, Volume 58, Issue 2, February 2026.
Abstract We study the equivariant Kuznetsov component KuG(X)$\mathrm{Ku}_G(X)$ of a general cubic fourfold X$X$ with a symplectic involution. We show that KuG(X)$\mathrm{Ku}_G(X)$ is equivalent to the derived category Db(S)$D^b(S)$ of a K3$K3$ surface S$S$, where S$S$ is given as a component of the fixed locus of the induced symplectic action on the ...

On varietal capability of Infinite direct products of groups [PDF]

International Journal of Group Theory, 2012
Recently, the authors gave some conditions under which a direct product of finitely many groups is V-capable if and only if each of its factors is V-capable for some varieties V.

Optimal Transport Autoregression to Forecast High‐Frequency Financial Data Distributions

Applied Stochastic Models in Business and Industry, Volume 42, Issue 1, January/February 2026.
ABSTRACT In this paper, we study the properties and performance of optimal transport autoregression in modeling and forecasting high‐frequency financial data distributions. We build on a class of univariate autoregressive transport models recently proposed in the literature (Zhu and Müller) where the distributional time series dynamics is modeled ...

On the Kolyvagin's formula, the Tate pairing associated to an isogeny, the local Artin map and the Hilberts symbol

Karpatsʹkì Matematičnì Publìkacìï, 2013
A proof of nondegeneracy of the Tate pairing and Kolyvagin's formula for elliptic curves with good reductions over an $n$-dimensional ($nleq 3$) pseudolocal field, the Tate pairing associated to an isogeny between abelian varieties over pseudolocal field

Hodge theory of abelian covers of algebraic varieties

Forum of Mathematics, Sigma
Motivated by classical Alexander invariants of affine hypersurface complements, we endow certain finite dimensional quotients of the homology of abelian covers of complex algebraic varieties with a canonical and functorial mixed Hodge structure (MHS ...

Irreducibility of Newton strata in ${GU}(1,n-1)$ Shimura varieties

Proceedings of the American Mathematical Society, Series B, 2014
Let 𝐿 be a quadratic imaginary field, inert at the rational prime 𝑝. Fix an integer 𝑛≥3, and let ℳ be the moduli space (in characteristic 𝓅) of principally polarized abelian varieties of dimension 𝓃 equipped with an action by 𝒪_{ℒ}

ARTINIAN \(\mathbf{M}\)-COMPLETE, \(\mathbf{M}\)-REDUCED, AND MINIMALLY \(\mathbf{M}\)-COMPLETE ASSOCIATIVE RINGS

Ural Mathematical Journal
In 1996, the first author defined analogs of the concepts of complete (divisible), reduced, and periodic abelian groups, well-known in the theory of abelian groups, for arbitrary varieties of algebras. In 2021, the first author proposed a modification of
