Event Title

Shadowing: Right Results from Wrong Numbers

Description

Numerical simulations are indispensable in the investigation of specific dynamical systems. Unfortunately, computer arithmetic with real numbers is not always exact. Since chaotic dynamical systems amplify small errors at an exponential rate, the results of most simulations are unreliable. Using computer simulations to illustrate his talk, Kocak will describe the method of shadowing for extracting mathematically rigorous results from erroneous numerical computations.
