Abstract:
We will first introduce the notion of the extended quotient of a space by a finite group acting on it, and provide examples. Next, we will recall the definition of the field F of p-adic numbers, and explain how extended quotients can be used to classify the representations of the group SL_n(F) of matrices with entries in F and determinant equal to 1. After a short presentation of the Langlands correspondence, we will build extended
quotients from Galois representations and compare them to the previous ones. This talk is a colloquium style talk and welcomes graduate students and
motivated undergraduate students.
