Discrete Approaches to Quantum Gravity
The construction of a consistent theory of quantum gravity is a problem in theoretical physics that has so far defied all attempts at resolution. Reviewed here are three major areas of research: gauge-theoretic approaches; quantum Regge calculus; and the method of dynamical triangulations.
