Let $p$ be a generically stable type, and call it idempotent when it is idempotent under the convolution product; call it generically transitive when it is concentrated on the type…

The automorphism-group idempotent fim measure conjecture. The following conditions are equivalent: (i) $\mu$ is idempotent with respect to the new convolution product; (ii) $\mu$ i…

Let $G$ be a connected Lie group. Write $P(G)$ for the space of probability measures on $G$, with convolution as its product. A measure $\mu\in P(G)$ is infinitely divisible if it…
