Symmetric Dellac configurations and symplectic/orthogonal flag varieties

13 Aug 2018 Bigeni Ange Feigin Evgeny

The goal of this paper is to study the link between the topology of the degenerate flag varieties and combinatorics of the Dellac configurations. We define three new classes of algebraic varieties closely related to the degenerate flag varieties of types A and C. The construction is based on the quiver Grassmannian realization of the degenerate flag varieties and odd symplectic and odd and even orthogonal groups... (read more)
