摘要:In this talk, we will consider an important class of Nakayama algebras $N_n(r)$ given by the path algebras of the equioriented quiver $A_n$ subject to the nilpotency degree $r$ for each sequence of $r$ consecutive arrows. We classify all the Nakayama algebras $N_n(r)$ having Fuchsian type, that is, derived equivalent to the extended canonical algebras. As a byproduct, we reprove the Nakayama algebras of piecewise hereditary type, which have been classified by Happel-Seidel earlier. This is joint work with Helmut Lenzing and Hagen Meltzer.
