Some homological properties of tensor and 
wreath products of quasi-hereditary algebras

Aaron Chan

Abstract. 
We show that taking the wreath product of a quasi-hereditary algebra
with symmetric group inherits several homological properties of the orig-
inal algebra, namely BGG duality, standard Koszulity, balancedness as
well as a condition which makes the Ext-algebra of its standard modules
a Koszul algebra.
