The Random Discrete Action for 2-Dimensional Spacetime
The Random Discrete Action 2-Dimensional Spacetime
2010/12/27
A one-parameter family of random variables, called the Discrete Action, is defined for a 2-dimensional Lorentzian spacetime of finite volume. The single parameter is a discreteness scale. The expecta...
Variable Survival Exponents in History-Dependent Random Walks: Hard Movable Reflector
Variable Survival Exponents History-Dependent Random Walks Hard Movable Reflector
2010/10/28
We review recent studies demonstrating a nonuniversal (continuously variable) survival exponent for historydependent random walks, and analyze a new example, the hard movable partial reflector. These ...
