This is the first of a two-volume set that provides a modern account of the representation
theory of finite dimensional associative algebras over an algebraically closed field. The …

We continue the Coxeter spectral study of the category 𝒰ℬigr m of loop-free edge-bipartite
(signed) graphs Δ, with m≥ 2 vertices, we started in [SIAM J. Discr. Math. 27 (2013), 827 …

In this two parts article with the same title we continue the Coxeter spectral study of the
category 𝒰ℬigr m of loop-free edge-bipartite (signed) graphs Δ, with m≥ 2 vertices, we …

Inspired by recent results of Ringel–Schmidmeier, Kussin–Lenzing–Meltzer, Xiao-Wu Chen,
and Pu Zhang, given a field K, m≥ 1, and a finite poset I≡(I,⪯) with a unique maximal …

We determine the representation type (wild, tame, polynomial growth) of the category fspr (I,
Fm) of filtered subprojective Fm-representations of a finite poset I in terms of m and I, where …

This article is an extended and completed version of the second part of the joint survey
lecture with Yu. Drozd on Cohen-Macaulay modules over Cohen-Macaulay algebras …

We give an algorithmic solution in a simple combinatorial data of Birkhoff0s type problem
studied in [22] and [25], for the category rep [TeX:] _ {ft}(I, K [t]/(t [TeX:]^ m)) of filtered I-chains …

We continue the study of finite connected loop-free edge-bipartite graphs Δ, with m≥ 3
vertices (a class of signed graphs), we started in Simson (2013)[48] and M. Gąsiorek et …

A complete list of positive Tits-sincere one-peak posets is provided by applying
combinatorial algorithms and computer calculations using Maple and Python. The problem …

The paper is an addition to our article Simson (2015)[37]. Given a field K, an integer m≥ 1,
and a finite poset I≡(I,⪯) with a unique maximal element⁎, we study the category M on (I, F …
