Quasi-hereditary algebras via generator-cogenerators of local   self-injective algebras and transfer of Ringel duality
  The dominant dimension of algebras in the class A of 1-quasi-hereditary algebras is at least two. By the Morita-Tachikawa Theorem this implies that A is related to a certain class B of algebras via bimodules satisfying the double centralizer condition. In this paper we specify the class B and the modules over algebras in B connected with A.   The class A is not closed under taking the Ringel-dual. However the dominant dimension of the Ringel-dual R(q) of a 1-quasi-hereditary algebra q is at least two. This fact induces a corresponding concept of modules over algebras in B which yield the algebras q and R(q) for q in A.
