In 2001, Yu gave an algebraic construction of supercuspidal representations of p-adic groups (now known to be exhaustive when the residual characteristic is sufficiently large—-Kim, Fintzen). There has since been a lot of progress towards explicitly constructing the local Langlands correspondence: Kazhdan-Varshavsky and DeBacker-Reeder (depth zero), Reeder and DeBacker-Spice (toral), and Kaletha (regular supercuspidals). In this talk, we present recent and ongoing work investigating a geometric counterpart to this story. This is based on joint work with Alexander Ivanov and joint work with Masao Oi.
