Abstract

This Chapter outlines the replica approach in Random Matrix Theory. Both fermionic and bosonic versions of the replica limit are introduced and its trickery is discussed. A brief overview of early heuristic treatments of zero-dimensional replica field theories is given to advocate an exact approach to replicas. The latter is presented in two elaborations: by viewing the β=2\beta=2 replica partition function as the Toda Lattice and by embedding the replica partition function into a more general theory of τ\tau functions.
