WebbIt is a remarkable fact that many of the universality laws discovered in the theory of random matrices appear in a variety of di erent models in statistical mechanics. A promi- nent example is the planar random growth models which belong to Kardar-Parisi-Zhang universality class. WebbThe effect of initial size on growth is determined by the value of β. For β = 1, the exponent of X is zero and size has no effect on growth. For β > 1, large firms grow faster than small ones, and vice versa for β < 1. The third element is a random growth term, εt, which enters the equation multiplicatively: t 1 t t t X X X

WebbThe universality is a property of a sequence ( pn) of symmetric probability density functions. Universality at x∗ means that for a suitably chosen sequence ( cn) the rescaled k -point correlation functions (6.2.2) have a specific limit as n →∞. The precise limit determines the universality class.
