Krasnosel'skii type formula and translation along trajectories method on the scale of fractional spaces

Piotr Kokocki

We provide global continuation principle of periodic solutions for the equation $u ˙ = - A u + F (t, u)$ , where $A : D (A) \to X$ is a sectorial operator on a Banach space $X$ and $F:[…

Homotopy invariants methods in the global dynamics of strongly damped wave equation

Piotr Kokocki

We are interested in the following differential equation $u ¨ (t) = - A u (t) - c A u ˙ (t) + λ u (t) + F (u (t))$ where $c > 0$ is a damping factor, $A$ is a sectorial operator and…
