1. A Numerical Study of the Lorenz and Lorenz-Stenflo Systems
Sammanfattning : In 1998 the Swedish mathematician Warwick Tucker used rigorous interval arithmetic and normal form theory to prove the existence of a strange attractor in the Lorenz system. In large parts, that proof consists of computations implemented and performed on a computer. LÄS MER
2. The Lorenz attractor exists
Sammanfattning : We prove that the Lorenz equations support a strange attractor, as conjectured by Edward Lorenz in 1963. We also prove that the attractor is robust, i.e., it persists under small perturbations of the coefficients in the underlying differential equations. LÄS MER
3. On the breakdown of regularity of invariant curves in quasi-periodically forced systems
Sammanfattning : In this thesis we study the process of torus collisions in one-parameter families of quasi-periodically forced dynamical systems. Specifically, we study the process whereby two invariant curves (homeomorphic to circles), one attracting and one repelling, bifurcate into a strange non-chaotic attractor. LÄS MER
