Relative dominant dimension and quality of split quasi-hereditary covers.

Description:  Dominant dimension of a finite-dimensional algebra A is a homological invariant measuring the connection between module categories A-mod and B-mod, where B is the endomorphism algebra of a faithful projective-injective A-module. In this talk, we will discuss generalisations of dominant dimension and how they can be used to measure the quality of split quasi-hereditary covers. The Schur algebra S(d, d) together with its faithful projective-injective module is a classic example of a split quasi-hereditary cover of the group algebra of the symmetric group on d letters.
