In the paper [MO], C. Menini and A. Orsatti introduced the notion of basic rzng of a locally
artinian Grothendieck category C. The basic ring of C is a right strictly linearly compact ring …

In this article we introduce the notion of cubical $(\omega, p) $-categories, for $ p\in\mathbb
N\cup\{\omega\} $. We show that the equivalence between globular and groupoid $\omega …

Abstract Problem 2 of [2] asks whether or not any left pseudo-artinian ring is also a strongly
left pseudo-artinian ring. Let us recall that a ring R is called left pseudo-artinian (resp …

We classify the thick subcategories of discrete derived categories. To do this we introduce
certain generating sets called ES-collections which correspond to configurations of non …

Ž. We recall that a ring R with identity is said to be of finite representation type if it is right
artinian and has only finitely many isomorphism Ž. Ž classes of finitely generated …

We prove for a large family of rings R that their λ-pure global dimension is greater than one
for each infinite regular cardinal λ. This answers in the negative a problem posed by …

We introduce the notion of star-symmetry for relations in a multi-pointed category and use it
to obtain a characterization of the projective covers of 2-star-permutable categories. This …

We present an abstract, categorical formulation of dependent functions in a fundamental
manner and independently from the Sigma-construction. For that, we define first the notion of …
