Quantum and affine Schubert calculus and Macdonald polynomials

Quantum and affine Schubert calculus and Macdonald polynomials

We definitively establish that the theory of symmetric Macdonald polynomials aligns with quantum and affine Schubert calculus using a discovery that distinguished weak chains can be identified by chains in the strong (Bruhat) order poset on the type-A affine Weyl group.We construct two one-parameter families of functions that respectively transition …
