Algebras of generalized quaternion type: biregular case
Karin Erdmann, Adam Hajduk, Adam Skowyrski
This paper provides the next step towards classification of algebras of generalized quaternion type. Previously algebras with 2-regular Gabriel quiver were classified (a quiver is…

Local structure of tame symmetric algebras of period four
Karin Erdmann, Adam Hajduk, Adam Skowyrski
In this paper we study the structure of Gabriel quivers of tame symmetric algebras of period four. More precisely, we focus on algebras having Gabriel quiver {\it biregular}, i.e.…

Tame symmetric algebras of period four
Karin Erdmann, Adam Hajduk, Adam Skowyrski
In this paper we are concerned with the structure of tame symmetric algebras of period four (TSP4 algebras, for short). We will mostly focus on the case when the Gabriel quiver of…
