Title：On formal degrees of supercuspidal unipotent representations
Abstract：Lusztig introduced the notion of unipotent representations of p-adic groups. He also gave a classification of these representations which fits the philosophy of Langlands. His classification was fulfiled by using affine Hecke algebras, cuspidal local systems and based on a case-by-case check. In this talk, we present a classification of supercuspidal unipotent representations of p-adic groups, using the formal degree as an invariant. If time permits, we will also discuss some corollaries of this classification. (Based on joint-work with Eric Opdam and Maarten Solleveld.)
