報(bào)告內(nèi)容簡(jiǎn)介:
In joint work with Lucas Mason-Brown and Dmytro Matvieievskyi (arXiv:2309.14853), we introduce an extended duality map that connects the covering spaces of nilpotent orbits in a complex semisimple Lie algebra with those in its Langlands dual. This construction generalizes earlier duality maps defined by Barbasch-Vogan and Sommers, and is closely related to Achar’s work. I will discuss how this extended duality interacts with unipotent representations, as well as its connections to symplectic duality. Part of this talk will also cover ongoing collaborative work with Daniel Juteau, Paul Levy, and Eric Sommers.
