Reformulation of the Hermitean 1-Matrix Model as an Effective Field Theory
(2009-07-22)
The formal Hermitean 1-matrix model is shown to be equivalent to an effective field theory. The correlation functions and the free energy of the matrix model correspond directly to the correlation functions and the free ...
Galois cohomology of Fontaine rings
