On Hele-Shaw problems arising as scaling limits

Complex Variables 2009-08-14 v2 Probability

Abstract

We discuss conjectural scaling limits of discrete 2-dimensional aggregation models conditioned on a semi-axis considered by Levine and Peres in arXiv:0712.3378. These are certain problems about Hele-Show flows. We study moment properties of their solutions, and solve some of them using conformal mappings. In particular, we predict the exact formula for the computer-generated shape on the left side of Fig. 4 in arXiv:0712.3378.
