Let (F, G, C) be a triple consisting of a local non-archimedean field F of characteristic a and residue field of characteristic p, a connected reductive linear group G defined over F and a field C of characteristic c. Either c = 0 or c is a prime number p or l≠p. The field of complex numbers is denoted by C.
I will give lectures on the basic theory of smooth C-representations of the reductive p-adic group G := G(F).According to the time, the audience and my energy, the lectures may include:
- a revised version of certain parts of my book [V96] where c ≠p, specially II.4 on rationality and integral structures.
- the irreducible cuspidal C-representations of G which are compactly induced, when c ≠p.
- the Bernstein center and the second adjoint theorem (when C = C the book [R10]) when c ≠p is banal ([V96] II.3.9).
- when c = p, cuspidal = supersingular [AHHV16] [OV18].
- when c = p and a = 0, the existence a subgroup Γ of G, discrete, cocompact modulo Z(G) and such that the smooth part of C[ΓZ(G)\G] admits an admissible irreducible cuspidal constituent [HKV19].
