Coxeter Functors and Gabriel’s Theorem İrem Yıldız, Dokuz Eylül University.Date: 6th of December, 2022, Tuesday, Time: 13:30 – 15:30.Place: Dokuz Eylül Univ., Tınaztepe Campus, Faculty of Science, Department of Mathematics, Room B206. Abstract: In this talk, we will introduce the basics of representation of quivers. We will define some functors which annihilate simples and carry indecomposables to indecomposables, which will help ... Read more Coxeter Functors and Gabriel’s Theorem

The Existence of Almost Split Sequences Fatma Kaynarca, Afyon Kocatepe University.Date: 29th of November, 2022, Tuesday, Time: 13.00 – 16.30.Place: Online-Sakai-Graduate Meetings Abstract: In this seminar, the existence of almost split sequences in the category of modules built on a finite-dimensional algebra will be proved with a functorial approach.

On Higher Commutators M. Pınar Eroğlu, Dokuz Eylül University. Date: 25th of October, 2022, Tuesday, Time: 13:30 - 15:30. Place: Dokuz Eylül Univ., Tınaztepe Campus, Faculty of Science, Department of Mathematics, Room B206. Abstract: A general result on higher commutators due to Herstein I.N. states that if A is a noncommutative simple algebra over a field of characteristic ... Read more On Higher Commutators

Almost Split and Minimal Morphisms        Fatma Kaynarca, Afyon Kocatepe University.Date: 21th of November, 2022, Tuesday, Time: 13.00 – 16.30.Place: Online-Sakai-Graduate Meetings Abstract: In this seminar, almost split morphisms, another concept that use to characterize almost split sequences, will be introduced and their relationship to irreducible morphisms and minimal morphisms will be examined.

Almost Split Sequences Fatma Kaynarca, Afyon Kocatepe University.Date: 15th of November, 2022, Tuesday, Time: 13.00 – 14.00.Place: Online-Sakai-Graduate Meetings Abstract: Almost split sequences arose from an attempt to understand the morphisms lying in the radical of a module category are minimal non-split short exact sequences. This sequences were introduced by Maurice Auslander and Idun Reitenin 1974-1975 and have ... Read more Almost Split Sequences
