Enrico Scalas -- PhD Studentship on Large deviation principles for Random walks in Random potential
We are pleased to offer this fully-funded PhD studentship, available in the Department of Mathematics at University of Sussex.
The project aims to understand the behaviour of various `rare events' associated with aspects of three types of growth processes, namely first and last passage percolation or random walks in random potential.
In random spatial processes such as these, we have always two sources of randomness.
First, we have a background random environment on a lattice that creates the `random medium' and then, under a fixed environment, we define a measure on lattice paths.
The goal of the proposed project is to understand not only the typical, but most importantly the atypical behaviour of these path measures and the paths themselves, under various conditions on the random environment.
The usual techniques necessary for such endeavours are drawn from various areas of Analysis (Real, Complex, Convex and Functional) and probabilistic techniques that when not completely general, are usually model dependent.
The PhD project will be under the supervision of Dr Nicos Georgiou.
