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