| Abstract: | The characteristic tilting modules of quasi-hereditary algebras which are dual extensions of directed monomial algebras are
explicitly constructed; and it is shown that the Ringel dual of the dual extension of an arbitrary hereditary algebra has
triangular decomposition and bipartite quiver. |
