Abstract
Let M be a smooth connected compact surface, P be either the real line R^1 or the circle S^1, and f:M-->P be a smooth mapping. In a previous series of papers for the case when f is a Morse map the author calculated the homotopy types of stabilizers and orbits of f with respect to the right action of the diffeomorphisms group of M. The present paper extends those calculations to a large class of maps M-->P with degenerate singularities satisfying certain set of axioms.

46 pages, 10 figures. v2. The paper is essentially rewritten and extended to new types of singularities. Due to the increased length, the last part of version 1 concerning reduction of calculations of the fundamental groups of orbits will be moved to another paper
