A bstract N M5-branes probing the intersection between the orbifold ℂ 2/Γ ADE and an E 8
wall give rise to 6d (1, 0) SCFTs known as ADE-type orbi-instantons. At fixed N and order of …

The notion of an extriangulated category gives a unification of existing theories in exact or
abelian categories and in triangulated categories. In this article, we develop Auslander …

Let R be a commutative Noetherian ring and M a finitely generated R-module. Under various
hypotheses, it is proved that the center of End R (M) coincides with the endomorphism ring …

We introduce a new notion of commutative noetherian local rings, which we call dominant.
We explore fundamental properties of dominant local rings and compare them with other …

Let R be an associative ring. This monograph deals with the right R-modules MR whose
endomorphism ring End (MR) is semilocal. More generally, let A be any preadditive …

We introduce the notion of Burch ideals and Burch rings. They are easy to define, and can
be viewed as generalization of many well-known concepts, for example integrally closed …

Weighted projective lines, introduced by Geigle and Lenzing in 1987, are important objects
in representation theory. They have tilting bundles, whose endomorphism algebras are the …

A bstract We propose a framework for treating F-theory directly, without resolving or
deforming its singularities. This allows us to explore new sectors of gauge theories …
