Some Homological Properties of Tensor and Wreath Products of Quasi-hereditary Algebras
arXiv:1212.2842
Abstract
We show that taking the wreath product of a quasi-hereditary algebra with symmetric group inherits several homological properties of the original algebra, namely BGG duality, standard Koszulity, balancedness as well as a condition which makes the Ext-algebra of its standard modules a Koszul algebra.
