       报告摘要：This is joint work with Helmut Lenzing and Hagen Meltzer. In this talk, we will consider a class of Nakayama algebras given by the path algebras of the equioriented quiver of type A subject to the nilpotency degree r for each sequence of r consecutive arrows. We classify all the Nakayama algebras having Fuchsian type, that is, derived equivalent to the extended canonical algebras, or equivalently, derived equivalent to a kind of stable category of vector bundles over weighted projective lines. This is achieved by constructing certain tilting complexes in the bounded derived category of coherent sheaves and also in the stable category of vector bundles for weighted projective lines, and the strategy of one-point extension and the perpendicular approach will be used. As a byproduct, we reprove the classification result of Nakayama algebras of piecewise hereditary type due to Happel—Seidel.
