About the Project

Requirements: The candidate should have a first class or upper second class honours degree, or a master’s degree (or equivalent qualification), in Mathematics, Computer Science or a related discipline. They should have some knowledge of Discrete Mathematics and a strong background in one or more of the following areas: Combinatorics, Probability Theory, Theory of Algorithms. Prior knowledge of the sandpile model is not expected. Evidence of good spoken and written English is essential. The candidate should have an IELTS score of 6.5 or above, if the first language is not English. This position is open to all qualified candidates irrespective of nationality.

Degree: The student will be awarded a PhD degree from the University of Liverpool (UK) upon successful completion of the program.

Project Description:

In the sandpile model, grains of sand are added at random to vertices on a graph. When the number of grains at a vertex reaches a certain threshold, that vertex becomes unstable. Unstable sites topple, sending grains of sand to their neighbours on the graph. A special vertex, called the sink, absorbs excess grains, and so the process eventually stabilises. The model was originally introduced in 1988 by Bak et al., and generalized and formalized by Dhar in 1990. Since then, it has attracted considerable interest in different fields - mathematics, computer science, statistical physics - with applications in areas such as earthquakes, the firings of brain cells, and forest fires. This project aims to study stochastic variants of this model, where an extra layer of randomness is introduced into the topplings of sites. Instead of sending grains to each of its neighbours, an unstable site chooses a random subset of these neighbours to end grains to, ignoring the others.
