Abstract

Let GG be a complex reductive group. For a smooth affine spherical GG-variety XX, assume that the unramified relative local Langlands conjecture of Ben-Zvi-Sakellaridis-Venkatesh for XX holds, the loop space LXLX is an L+GL^+G--placid ind--scheme, and there exists a dimension theory for LXLX, we give a spectral description of a full subcategory of Iwahori equivariant D-modules on LXLX in terms of the relative Langlands dual of XX, confirming a slight variant of the tamely ramified local relative Langlands conjecture proposed by Devalapurkar.
