On the structure of the set of bifurcation points of periodic solutions for multiparameter Hamiltonian systems

Wiktor Radzki

This paper deals with periodic solutions of the Hamilton equation with many parameters. Theorems on global bifurcation of solutions with periods $2 π / j,$ $j \in N,$ from a st…

Degenerate bifurcation points of periodic solutions of autonomous Hamiltonian systems

W. Radzki, S. Rybicki

We study connected branches of non-constant { $2 π$ -pe}riodic solutions of the Hamilton equation \begin{displaymath} \dot{x}(t)=λJ\nabla H(x(t)), \end{displaymath} where $λ\in\halfli…
