A remark on Leclerc's Frobenius categories [PDF]
, 2017 Leclerc recently studied certain Frobenius categories in connection with cluster algebra structures on coordinate rings of intersections of opposite Schubert cells.

Mittag-Leffler modules and Frobenius
, 2023 We systematically study the intersection flatness and Ohm-Rush properties for modules over a commutative ring, drawing inspiration from the work of Ohm and Rush and of Hochster and Jeffries.

The asymptotic behavior of Frobenius direct images of rings of invariants [PDF]
, 2016 We define the Frobenius limit of a module over a ring of prime characteristic to be the limit of the normalized Frobenius direct images in a certain Grothendieck group.

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 ...

Bicontinuous Isomorphisms between Two Closed Left Ideals of a Compact Dual Ring
, 1966 A quasi-Frobenius ring is a ring with minimum condition satisfying the conditions r(l)H)) = H and l(r(L)) = L for right ideals H and left ideals L where r(S) (l(S)) denotes the right (left) annihilator of a subset S of the ring.

, 2005 It is proved here that a ring R is right pseudo-Frobenius if and only if R is a right Kasch ring such that the second right singular ideal is injective.

Quasi-Frobenius quotient rings
, 1991 Let R be an associative (not necessarily commutative) ring with unit. The study of flat left R-modules permits to achieve homological characterizations for some kinds of rings (regular Von Neumann, hereditary).

A Fracture Mechanics-based Method for Prediction of Cracking of Circular and Elliptical Concrete Rings under Restrained Shrinkage [PDF]
, 2014 This article has been made available through the Brunel Open Access Publishing Fund.A new experimental method, utilizing elliptical ring specimens, is developed for assessing the likelihood of cracking and cracking age of concrete subject to restrained ...

Partial normalizations of coxeter arrangements and discriminants [PDF]
, 2012 We study natural partial normalization spaces of Coxeter arrangements and discriminants and relate their geometry to representation theory. The underlying ring structures arise from Dubrovin’s Frobenius manifold structure which is lifted (without unit)
