Query: Internal Diffusion-Limited aggregation with uniform starting points   We study internal diffusion-limited aggregation with random starting points
on Z^d. In this model, each new particle starts from a vertex chosen uniformly
at random on the existing aggregate. We prove that the limiting shape of the
aggregate is a Euclidean ball.
