Web2 TAKUMAAIHARA (1) Symmetric special biserial algebras; (2) Special quivers with cycle-decomposition (SB quivers); (3) Brauer graphs. 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 … WebTo divide into two equal parts. We can bisect line segments, angles, and more.

WebFeb 1, 1998 · THE STRUCTURE OF BISERIAL ALGEBRAS - Volume 57 Issue 1. By an algebra Λ we mean an associative k-algebra with identity, where k is an algebraically closed field. All algebras are assumed to be finite dimensional over k (except the path algebra kQ).An algebra is said to be biserial if every indecomposable projective left or right Λ … Webalgebras of finite groups, Hecke algebras and special biserial algebras. The last family is particularly interesting, as large parts of the representation theory and (co)homology are well-studied and understood. The class of symmetric special biserial algebras coincides with the class of Brauer graph algebras [32].
