[Todos CMAT] Seminario de álgebra del IMERL

[Ana González]

Estimados,
este viernes vamos a poder escuchar a Sonia Fernandes de la Universidade
Federal de Viçosa.

Nos va hablar sobre:

Título: *SHAPES OF AUSLANDER-REITEN TRIANGLES*

Resumen:* In this talk, we will speak of the shape of the Auslander-**Reiten
triangles in the bounded derived category of the module cat**egory of a
finite dimensional non-semisimple algebra over a field **k. So, we have
given a characterization of the mapping cone of an **Auslander-Reiten
triangle. The characterization depends strongly **on the three kinds of
irreducible maps. And this characterization*
*allow us to simplify the mapping cone and also to give a complete
**characterization
of Auslander-Reiten triangles.*


Nos vemos el viernes en el salón de seminarios del IMERL a las 11:15.

Saludos
Ana
