1. Propagation of Chaos for Kac-like Particle Systems
Abstract : This thesis concerns various aspects of the Kac model. The Kac model is a Markov jump process for a particle system where the total kinetic energy of the system is conserved. This particle model is connected to a limiting equation, describing the evolution of a one-particle density, when the numbers of particles tends to infinity. READ MORE

2. Life histories and population dynamics
Abstract : During the last decades there has been a growing interest and attention to random variation in population densities and their causes. It has been shown that even in constant environments (deterministic population growth) the dynamics of populations can display random like behaviour depending on parameter values. READ MORE

3. Get a grip on chaos : Tailored measures for complex systems on surfaces
Abstract : Complex systems are ubiquitous in physics, biology and mathematics. This thesis is concerned with describing and understanding complex systems. Some new concepts about how large systems can be viewed in a lower dimensional framework are proposed. The systems presented are examples from ecology and chemistry. READ MORE

4. Lattice Boltzmann simulations of tracer diffusion in microswimmer suspensions
Abstract : Suspensions of microswimmers are a class of systems inherently out of equilibrium, due to the mechanical work continuously performed by a large number of active agents. Biological examples are plentiful, as many aquatic microorganisms have the ability to propel themselves. READ MORE
