This method creates a GKMVariety that represent a generalized Schubert variety of a generalized flag variety. The following example is the Schubert variety of projective lines in $\mathbb P^3$ meeting a distinguished point.
i1 : X = generalizedSchubertVariety(generalizedFlagVariety("A",3,{2}),{set{0,3}}) o1 = a GKM variety with an action of a 4-dimensional torus o1 : GKMVariety |
The object generalizedSchubertVariety is a method function.
