Gady Kozma is an Israeli mathematician. Kozma was promoted in 2001 at the University of Tel Aviv with Alexander Olevskii. He is a scientist at the Weizmann Institute . In 2005, he demonstrated the existence of the scaling limit value (ie for increasingly finer lattices) of Loop Erased Random Walk (LERW) in three dimensions and its invariance under rotations and dilations.[1] 

LERW consists of a random walk, whose loops, which form when it intersects itself, are removed. He was introduced to the study of self-avoiding random walk by Gregory Lawler in 1980, but is an independent model in another universality class. In D = 2, conformal invariance was proved by Lawler, Oded Schramm and Wendelin Werner (with Schramm Loewner Evolution, SLE) in 2004, four and more dimensions were treated by Lawler, the scale limiting value is Brownian movement, in four dimensions - With logarithmic correction. Kozma treated the two-dimensional case in 2002 with a new method. In addition to probability theory, he also deals with Fourier series.[2] 

In 2008 he received the Erdős Prize and in 2010 the Rollo-Davidson Prize.
