Homology of loops on a splitting-rank symmetric space via the Geometric Satake for real groups

Abstract

Using Nadler's Geometric Satake Equivalence for real reductive groups, we obtain a description of the equivariant homology of the loop space of splitting-rank symmetric spaces in terms of the relative dual group of the space. The description is in line with Yun and Zhu's calculation for the loop space of a compact Lie group. The formula hints at a relative duality for these spaces.
