Extention cohomological fields theories and noncommutative Frobenius manifolds
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 spheres and disks with punctures. It is described by
a formal tensor series, satisfying to some system of "differential equations".
In points of convergence the tensor series generate special noncommutative
analogues of Frobenius algebras, describing 'Open-Closed' Topological Field
Theories.Comment: 19 pages, LaTe
