Existence and continuation of solutions for a nonlinear Neumann problem
K. Muchewicz, S. Rybicki
In this article we study the existence, continuation and bifurcation from infinity of nonconstant solutions for a nonlinear Neumann problem. We apply the Leray-Schauder degree and…

Degenerate bifurcation points of periodic solutions of autonomous Hamiltonian systems
W. Radzki, S. Rybicki
We study connected branches of non-constant {-pe}riodic solutions of the Hamilton equation \begin{displaymath} \dot{x}(t)=λJ\nabla H(x(t)), \end{displaymath} where $λ\in\halfli…
