A classification of Prüfer domains of integer‐valued polynomials on algebras

Bulletin of the London Mathematical Society, Volume 58, Issue 4, April 2026.
Abstract Let D$D$ be an integrally closed domain with quotient field K$K$ and A$A$ a torsion‐free D$D$‐algebra that is finitely generated as a D$D$‐module and such that A∩K=D$A\cap K=D$. We give a complete classification of those D$D$ and A$A$ for which the ring IntK(A)={f∈K[X]∣f(A)⊆A}$\textnormal {Int}_K(A)=\lbrace f\in K[X] \mid f(A)\subseteq A ...

Traces of Hecke operators on Drinfeld modular forms for GL2(Fq[T])$\operatorname{GL}_2(\mathbb {F}_q[T])$

Mathematika, Volume 72, Issue 2, April 2026.
Abstract In this paper, we study traces of Hecke operators on Drinfeld modular forms of level 1 in the case A=Fq[T]$A = \mathbb {F}_q[T]$. We deduce closed‐form expressions for traces of Hecke operators corresponding to primes of degree at most 2 and provide algorithms for primes of higher degree.

Outer Galois theory prime rings

Rocky Mountain Journal of Mathematics, 1984
An outer Galois theory for prime rings can be obtained as a special case of the Galois theory developed by \textit{V. K. Kharchenko} [Algebra Logika 16, 313-363 (1977; Zbl 0397.16037)] for semiprime rings. The authors, however, give a direct derivation of the Galois correspondence in this case.

Extensions of tautological rings and motivic structures in the cohomology of ${\overline {\mathcal {M}}}_{g,n}$

Forum of Mathematics, Pi
We study collections of subrings of $H^*({\overline {\mathcal {M}}}_{g,n})$ that are closed under the tautological operations that map cohomology classes on moduli spaces of smaller dimension to those on moduli spaces of larger dimension and ...

Peculiarities of Applying Partial Convolutions to the Computation of Reduced Numerical Convolutions

Applied Sciences
A method is proposed that reduces the computation of the reduced digital convolution operation to a set of independent convolutions computed in Galois fields.
