SOME BIFURCATION RESULTS IN NEAR-HAMILTONIAN SYSTEMS WITH FINITE-ORDER SMOOTHNESS

This paper presents a systematic survey of bifurcation theory for near-Hamiltonian systems with finite-order smoothness. Unlike the classical $C^{\infty}$ or $C^{\omega}$ framework, we collect some known results on limit cycle bifurcations for planar systems with finite-order smo...
