Existence of periodic solutions for the Lotka-Volterra type systems
H. Hirano, S. Rybicki
In this paper we prove the existence of non-stationary periodic solutions of delay Lotka-Volterra equations. In the proofs we use the degree for -equivariant maps.

Existence and continuation of periodic solutions of Newtonian systems
J. Fura, A. Ratajczak, S. Rybicki
In this article we study the existence and the continuation of periodic solutions of autonomous Newtonian systems. To prove the results we apply the infinite-dimensional version of…
