Main Topics

Ecology

phytoplankton, competition, coexistence, survival, heterogeneous environment

Under what conditions will a population survive in a heterogeneous environment and when can a new species invade in the presence of another?

Evolution

coevolutionary motion, interspecific interactions, hamiltonian systems

One species might evolve to better fit a landscape of a niche space, but what will happen if this landscape dynamically changes, reflecting locations of all other species?

Fractals

Diffusion limited aggregation, DLA, fractal dimension, deposition

To what extend can we predict the structure of a cluster growing on a specially assembled substrate

Billiards

Lorentz gas, stadium, Fermi acceleration, stochastic and regular dynamics

In billiards with perturbed boundaries a billiard ball will change its velocity, which is know as Fermi acceleration. What dynamical properties of unperturbed billiards are important to achieve high velocities of the billiard ball
