Morse decomposition for semi-dynamical systems with an application to systems of state-dependent delay differential equations
István Balázs, Ãbel Garab, Teresa Rauscher
Understanding the structure of the global attractor is crucial in the field of dynamical systems, where Morse decompositions provide a powerful tool by partitioning the attractor i…

Discrete Lyapunov functional for cyclic systems of differential equations with time-variable or state-dependent delay
István Balázs, Ãbel Garab
We consider nonautonomous cyclic systems of delay differential equations with variable delay. Under suitable feedback assumptions, we define an (integer valued) Lyapunov functional…
