Comments to the problem on branching of periodical solutions at Andronov-Hopf bifurcation in differential equations with degenerated operator before the derivative

A. A. Kyashkin1, B. V. Loginov2, P. A. Shamanaev3

AnnotationBy the methods of branching theory of solutions to nonlinear equations it is investigated the perturbation problem for $n$-multiple pair of pure imaginary eigenvalues at the presence of generalized Jordan chains at Poincar\'{e}-Andronov-Hopf bifurcation.
KeywordsAndronov-Hopf bifurcation, perturbation of the critical pairs of eigenvalues.
