Closures of K-orbits in the flag variety for SU*(2n)
William M. McGovern
We characterize the Sp_{2n} orbits in the flag variety for SL_{2n} with rationally smooth closure via a pattern avoidance criterion, also showing that the singular and rationally s…

Closures of K-orbits in the flag variety for U(p,q)
William M. McGovern
We classify the GL_p x GL_q-orbits in the flag variety for GL_{p+q} with rationally smooth closure, showing that they are all either already closed or are pullbacks from orbits wit…

Pattern avoidance and smoothness of closures for orbits of a symmetric subgroup in the flag variety
William M. McGovern, Peter E. Trapa
We give a pattern avoidance criterion to classify the orbits of Sp(p,C) x Sp(q,C) (resp. GL(n,C)) on the flag variety of type C_{p+q} (resp. D_n) with rationally smooth closure. We…
