Endoscopy for unitary symmetric spaces
Spencer Leslie
Motivated by global applications, we propose a theory of relative endoscopic data and transfer factors for the symmetric pair over a local field. We then…

An analogue of the Grothendieck-Springer resolution for symmetric spaces
Spencer Leslie
Motivated by questions in the study of relative trace formulae, we construct a generalization of Grothendieck's simultaneous resolution over the regular locus of certain symmetric…

Resonant Mirković-Vilonen polytopes and formulas for highest-weight characters
Spencer Leslie
Formulas for the product of an irreducible character of a complex Lie group and a deformation of the Weyl denominator as a sum over the crystal go back to…
