Brownian-motion conjecture. Under assumptions … , Theorem $$ can be strengthened so that the random walk on a discrete point process, under appropriate scaling, converges to Browni…
Infinite-second-moment examples conjecture. There exist random walks on discrete point processes that satisfy a Central Limit Theorem but do not have all of their second moments fi…
Finite-second-moment conjecture. Theorem $$ remains true under the weaker assumption that only the second moments are finite.
