Biserial algebras and graphs
Web[FS07]. Recently, Brauer graph algebras also appeared in connection with dessins d’enfants [MS20]. Over an algebraically closed field the class of Brauer graph algebras coincides with the class of symmetric special biserial algebras [AG05, Sch15], whose representation theory has been studied quite extensively.

We introduce mutation of SB quivers (see Definition 3.2, 3.5 and 3.8), which is similar to Fomin-Zelevinsky quiver-mutation [FZ]. Moreover we will show that mutation of SB quivers corresponds to a certain operation on …
