Two-step tilting for standardly stratified algebras

We study the class of standardly stratified algebras introduced by Cline, Parshall and Scott, and its subclass of the
 so-called weakly properly stratified algebras, which generalizes the
 class of properly stratified algebras introduced by Dlab. We characterize when the Ringel dual...

description We study the class of standardly stratified algebras introduced by Cline, Parshall and Scott, and its subclass of the
 so-called weakly properly stratified algebras, which generalizes the
 class of properly stratified algebras introduced by Dlab. We characterize when the Ringel dual of a standardly stratified algebra is
 weakly properly stratified and show the existence of a two-step tilting module. This allows us to calculate the finitistic dimension of
 such algebras. Finally, we also give a construction showing that
 each finite partially pre-ordered set gives rise to a weakly properly
 stratified algebras with a simple preserving duality.
