Generalization of Lyapunov Center Theorem for Hamiltonian systems via normal forms theory

Autor: Gołębiewska, A., Rybicki, S.

In this article we formulate and prove sufficient conditions for the existence of trajectories of nonstationary periodic solutions of autonomous Hamiltonian systems in a neighbourhood of equilibria. It is worth pointing out that assumptions of some w

Summary: Herein, we present an ex vivo approach to study glioblastoma (GBM) cell motility in viable mouse brain slice cultures, closely mimicking in vivo features. We detail the preparation and culturing of mouse brain slices followed by tumor cell i

An optimal control for a dynamical system optimizes a certain objective function. Here we consider the construction of an optimal control for a stochastic dynamical system with a random structure, Poisson perturbations and random jumps, which makes t
