Torsion and Torsion-Free Classes Arising Through Objects Of Finite Type in a Grothendieck Category Sinem Odabaşı, Universidad de Murcia. Date: 3th of January, 2023, Tuesday, Time: 13.00 - 14.30. Place: Online-Join Zoom Meeting (https://zoom.us/j/99412179515?pwd=bUlLdStFaVpjMHhWb21LaFlRMWI1Zz09) Meeting ID: 994 1217 9515 Passcode: 553266 Abstract: In a module category, the class FPn(R) of the so-called finitely n-presented left R-modules induces two crucial classes In(R) and Fn(Rop) of left FPn-injective and right FPn-flat ...

On coGalois Groups Canan Özeren, Dokuz Eylül University.Date: 26th of December, 2022, Tuesday, Time: 13:30 – 15:30.Place: Dokuz Eylül Univ., Tınaztepe Campus, Faculty of Science, Department of Mathematics, Room B206. Abstract:Torsion-free covers exist for abelian groups (see [1]).The coGalois group of a torsion-free cover of an abelian group is defined in [2] as the group of s.t. and ...

Coxeter Functors and Gabriel’s Theorem III İrem Yıldız, Dokuz Eylül University.Date: 20th 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 III
