Helmut Lenzing, José Antonio de la Peña
We investigate the spectral properties of a new class of finite dimensional algebras, called extended canonical. In particular, we show that at most four eigenvalues of the Coxeter…

Extended canonical algebras and Fuchsian singularities
Helmut Lenzing, José Antonio de la Peña
We introduce a new class of finite dimensional algebras, called extended canonical, investigate their derived categories and study the spectral behavior of their Coxeter transforma…
