SUMMARY:"Laplacian Growth"
DESCRIPTION:Featuring Mark Mineev-Weinstein\, Natal\nHosted by: Anatoli Pol
	kovnikov\n\nPart of the Condensed Matter Theory Seminar Series.\n\nNumerous
	 unstable non-equilibrium physical processes produce a multitude of rich co
	mplex patterns\, both compact and (more often) fractal.  Shapes of patterns
	 in a long time limit include fingers in porous media\, dendritic trees in 
	crystallization\, fractals in bacterial colonies and malignant tissues\, ri
	ver networks\, and other bio- and geo- systems. The patterns are often univ
	ersal and reproducible. Geometry and dynamics of these forms present great 
	challenges\, because mathematical treatment of nonlinear\, non-equilibrium\
	, dissipative\, and unstable dynamical systems is\, as a rule\, very diffic
	ult\, if possible at all.  While many impressive experimental and computati
	onal results were accumulated\, powerful analytic methods for these systems
	 were very limited until recently. Remarkably\, many of these growth proces
	ses were reduced (after some idealization) to a mathematical formulation\, 
	which owns rich\, powerful and beautiful integrable structure\, and reveals
	 deep connections with other exact disciplines\, lying far from non-equilib
	rium growth. In physics the examples include quantum gravity\, quantum Hall
	 effect\, and phase transitions. In classical mathematics\, this structure 
	was found to be deeply interconnected with such fields as the inverse poten
	tial problem\, classical moments\, orthogonal polynomials\, complex analysi
	s\, and algebraic geometry. In modern mathematical physics we established t
	ight relations of nonlinear growth to integrable hierarchies and deformatio
	ns\, normal random matrices\, stochastic growth\, and conformal theory. Thi
	s mathematical structure made possible to see many outstanding problems in 
	a new light and solve several long-standing challenges in pattern formation
	 and in mathematical physics.\n\nDuring the talk I will provide brief histo
	ry with key experiments and paradigms in the field\, make short surveys of 
	mathematics mentioned above\, expose the integrable structure hidden behind
	 the interface dynamics\, and will present major results up to date in this
	 rapidly growing field.
