Date and Time:
For efficient and physically reliable numerical computations for time dependent differential equations it is very important to find positively invariant subsets of the state space and determine time step sizes of the numerical method that guarantee this. In this talk, we present the state-of-the-art theory and novel approaches beyond it to find positively invariant sets and the suitable time step sizes via optimization techniques.
