ρ-MODULAR REPRESENTATIONS OF ρ-ADIC GROUPS

These notes are an introduction to the ρ-modular (or “mod-ρ”) repre-sentation theory of ρ-adic reductive groups. We will focus on the group GL₂(ℚρ), but we try to provide statements that generalize to an arbitrary ρ-adic reductive group G (for example, GL_n(ℚρ)).
