INTERFACE STRUCTURE IN COLORED DLA MODEL

We propose a model for the simultaneous diffusion-limited growth of tw o clusters A and B, where the growth of one cluster screens the growth of the other one. We consider the possibility that the A and B duster s can penetrate into each other in course of their growth in different spatial dimensions and express the conjecture that the A-B boundary i s flat in all dimensions. Using an electrostatic analogy, we compute s ome spatial characteristics of the clusters. (C) 1996 American Institu te of Physics.
