Sergei M. Natanzon, Aleksandr Yu. Orlov
We explain how Gaussian integrals over ensemble of complex matrices with source matrices generate Hurwitz numbers of the most general type, namely, Hurwitz numbers with arbitrary o…

Extention cohomological fields theories and noncommutative Frobenius manifolds
S. M. Natanzon
We construct some extension ({\it Stable Field Theory}) of Cohomological Field Theory. The Stable Field Theory is a system of homomorphisms to some vector spaces generated by spher…
