A Gröbner basis for Kazhdan-Lusztig ideals of the flag variety of affine type A
B Elek, D Huang - Advances in Mathematics, 2024 - Elsevier
A Kazhdan-Lusztig variety is the intersection of a locally-closed Schubert cell with an
opposite Schubert variety in a flag variety. We present a linear parametrization of the …

In this paper we explicitly compute all Littlewood–Richardson coefficients for semisimple
and Kac–Moody groups G, that is, the structure constants (also known as the Schubert …
