Let $\Gamma$ be a higher-rank lattice and let a character mean the character object considered in the source. Connes' character rigidity conjecture. Every character of $\Gamma$ is…

Let $\Gamma$ be an irreducible higher-rank lattice. The charfiniteness conjecture. The group $\Gamma$ is charfinite, in the sense of the character-rigidity terminology used in the…
