Computer-assisted proofs in dynamics

Category: Veranstaltung
Location: Hubland Nord, Geb. 40, 01.003
Speaker: MSc Jakub Banaśkiewicz, Jagiellonian University in Kraków

The talk will be an introduction to computer-assisted proofs in dynamics. I will start by describing interval arithmetic and compare it with the standard floating-point arithmetic.
Then we will discuss the rigorous numerical methods and their applications. Mainly, I will focus on the rigorous methods for solving ODEs.  Then, I will tell you about rigorous numerical for dissipative partial differential equations. With the use of these techniques, we have proven the existence of periodic orbit for Brusselator system with diffusion and Chafee-Infante equation, which are the main results of my PhD dissertation.
