Growth models, in which a planar domain increases its area with boundary speed proportional to the gradient of a harmonic function, are deceivingly simple, on one hand because they describe a very large class of phenomena, and on the other because they lead to subtle mathematical questions.
The talk will survey some of the physical situations which are described by such models, and will present elements of the mathematical content of such theories. It will be shown how critical phenomena associated with such growth processes (bubble burst, branching, droplet break-off, etc.) can be completely understood through a unitary theoretical framework.
