- W2580817131 abstract "In their previous work, S. Koenig, S. Ovsienko and the second author showedthat every quasi-hereditary algebra is Morita equivalent to the right algebra(i.e. the opposite algebra of the left dual) of a coring. Let $V$ be an$A$-coring whose right algebra $R$ is quasi-hereditary. In this paper, we givea combinatorial description of a $B$-coring $W$ whose right algebra is given bythe Ringel dual of $R$. We apply our results to obtain in small examplesrestrictions on the $A_infty$-structure of the $textrm{Ext}$-algebra ofstandard modules over a class of quasi-hereditary algebras related tobirational morphisms of smooth surfaces." @default.
