March 4, Title:   $\varphi$ Dimension of Nakayama Algebras

Abstract: $\varphi$ dimension of an artin algebra can be considered as a generalization of global dimension. We show the following: $\varphi$ dimension of cyclic Nakayama algebra of infinite global dimension is always even.

March 11, Title :  Homological Properties of Nakayama Algebras

Abstract: We introduce syzygy filtration method for cyclic Nakayama algebras. Immediate applications of it are the following:

  1. Difference of $\varpi$ dimension and finitistic dimension is at most one.
  2. If algebra is Gorenstein, then $\varphi$ dimension is equal to Gorenstein dimension.
