Multiplicity of limit cycles that appear after perturbations of hyperbolic polycycles

Dynamical Systems 2022-01-27 v2

Abstract

We consider the multiplicity of limit cycles that appear when a hyperbolic polycycle is perturbed. We prove, in particular, that if such unfolding happens in generic finite-parameter families, the multiplicity of every new limit cycle does not exceed the number of separatrix connections in the polycycle.
