The Frobenius Complexity of Hibi Rings
, 2018 We study the Frobenius complexity of Hibi rings over fields of characteristic p. In particular, for a certain class of Hibi rings (which we call anticanonical level), we compute the limit of the Frobenius complexity as p goes to infinity.

Hypergeometric motives from Euler integral representations
Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.Abstract We revisit certain one‐parameter families of affine covers arising naturally from Euler's integral representation of hypergeometric functions. We introduce a partial compactification of this family. We show that the zeta function of the fibers in the family can be written as an explicit product of L$L$‐series attached to nondegenerate ...

, 1970 The theory of near-rings has arisen in a variety of ways. There is a natural desire to generalise the theory of rings and skew fields by relaxing some of their defining axioms.

Non‐Linear Reduced Order Modelling of Transonic Potential Flows for Fast Aerodynamic Analysis
International Journal for Numerical Methods in Engineering, Volume 127, Issue 2, 30 January 2026.ABSTRACT This work presents a physics‐based reduced order modelling (ROM) framework for the efficient simulation of steady transonic potential flows around aerodynamic configurations. The approach leverages proper orthogonal decomposition and a least‐squares Petrov‐Galerkin (LSPG) projection to construct intrusive ROMs for the full potential equation ...

IET Systems Biology, Volume 20, Issue 1, January/December 2026.This study introduces a novel method to identify rational‐function dynamics in biological networks, overcoming the limitations of existing approaches like SINDy. By applying singular value decomposition to a mixed library of state and derivative terms, the method efficiently extracts the implicit model structure from data.

Exponent matrices and Frobenius rings
, 2014 We give a survey of results connecting the exponent matrices with Frobenius rings. In particular, we prove that for any parmutation σ ∈ Sn there exists a countable set of indecomposable Frobenius semidistributive rings Am with Nakayama permutation σ.The ...

The extension theorem for bi-invariant weights over Frobenius rings and Frobenius bimodules
, 2019 We give a sufficient condition for a bi-invariant weight on a Frobenius bimodule to satisfy the extension property. This condition applies to bi-invariant weights on a finite Frobenius ring as a special case.

Filtered quasi-Frobenius rings
Mathematische Zeitschrift, 1968 The main object of this note is to prove that a filtered ringA is quasi-Frobenius, if its associated graded ring E ~ (A) is quasi-Frobenius (Theorem 1). In w 1, we discuss some generalities on quasi-Frobenius rings. In w 2, given a filtered ring A such that F~A=A for some n, we construct an injective, filtered Amodule F* such that E ~ (F*) is E ~ (A ...

TRIANGULAR MATRIX REPRESENTATIONS OF SKEW MONOID RINGS
, 2010 Let R be a ring and S a u.p.-monoid. Assume that there is a monoid homomorphism α : S → Aut (R). Suppose that α is weakly rigid and lR(Ra) is pure as a left ideal of R for every element a ∈ R.
