Globally analytic principal series representation and Langlands base change

Jishnu Ray

Vol. 307 (2020), No. 2, 455–490

S. Orlik and M. Strauch have studied locally analytic principal series representation for general p-adic reductive groups generalizing an earlier work of P. Schneider for GL(2) and related the condition of irreducibility of such locally analytic representation with that of a suitable Verma module. We take the case of GL(n) and study the globally analytic principal series representation under the action of the pro-p Iwahori subgroup of GL(n, p), following the notion of globally analytic representations introduced by M. Emerton. Furthermore, we relate the condition of irreducibility of our globally analytic principal series to that of a Verma module. Finally, using the Steinberg tensor product theorem, we construct the Langlands base change of our globally analytic principal series to a finite unramified extension of p.
