原始语种摘要: In this paper we consider the problem of bifurcation of extremals of SO(2)-invariant (i.e., with circular symmetry) Fredholm functional near a steady-state point with a double-resonance (i.e., with two independent resonance relations). The main method of investigation is a variational modification of the Lyapunov-Schmidt reduction. It allows us to find a normal form of key functions of functionals. J. Mather’s condition on a finite determinacy of a smooth map germ gives a simpler representation of the key function. Further bifurcational analysis of branching extremals reduces the problem to analysis of boundary and corner singularities via the secondary reduction.
