Flag varieties and schubert calculus

WebSchubert calculus is the study of flag varieties, which are quotients of algebraic groups (usually complex semisimple, but sometimes over the real numbers or even finite fields) by parabolic subgroups. ... Most modern treatments of the Schubert calculus typically write about the cohomology ring of the Grassmannian. They also write, almost as an ... WebWe establish an equivariant quantum Giambelli formula for partial flag varieties. The answer is given in terms of a specialization of universal double Schubert polynomials. Along the way, we give new proofs of the pres…
