O. Shochet et E. Benjacob, COEXISTENCE OF MORPHOLOGIES IN DIFFUSIVE PATTERNING, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 48(6), 1993, pp. 180004168-180004171
We discuss a proposed morphology-selection principle and the implied c
oncepts of the morphology diagram and morphology transitions. We use a
diffusion transition scheme to demonstrate that morphology transition
s can be characterized by a change in the functional form of the growt
h velocities and a change in the the envelope shapes. Our main support
of the present picture is the demonstration of the coexistence of two
morphologies, tip splitting and dendritic growth.
