Dendrites are the typical patterns for many anisotropic growth processes. A detailed understanding of their dynamics appears to be crucial for a proper classification of various growth morphologies. In particular the morphology transitions occurring for varying anisotropy were predicted to...

The evolution and selection of fractal and compact growth patterns is described. As a particular example the growth of a supercritical nucleus occurring during typical first-order phase transitions and its behaviour at long times and large lengths is discussed. While the generic growth mode is...
