Contractions of product density operators of systems of identical fermions and bosons
Wiktor Radzki
Recurrence and explicit formulae for contractions (partial traces) of antisymmetric and symmetric products of identical trace class operators are derived. Contractions of product d…

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 from a st…

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…
