A Note On Coinduction Functors between Categories of Comodules for Corings
Jawad Abuhlail
In this note we consider different versions of coinduction functors between categories of comodules for corings induced by a morphism of corings. In particular we introduce a new v…
Essential domains and two conjectures in dimension theory
Marco Fontana, Salah Kabbaj
This note investigates two long-standing conjectures on the Krull dimension of integer-valued polynomial rings and of polynomial rings, respectively, in the context of (locally) es…
On the Linear Weak Topology and Dual Pairings over Rings
Jawad Y. Abuhlail
In this note we study the weak topology on paired modules over a (not necessarily commutative) ground ring. Over QF rings we are able to recover most of the well known properties o…
Semicrossed products generated by two commuting automorphisms
Mohammed Ridha Alaimia, Justin R. Peters
We study the semicrossed product of a finite dimensional C^*-algebra by two types of commuting automorphisms, and identify them with matrix algebras of analytic functions in two va…
