Description:
This course offers an introduction to model theoretically random walks movement in space and time of agents, being they humans, biological organisms or robots, both in homogeneous and heterogeneous space. The focus is on the mathematical description of the random nature of movement paths (not on the physics of locomotion) and the interactions of a random walk with the heterogeneity of the environment and with fixed or moving targets. The lectures will cover mainly space-time discrete representations but connections to the space-time continuous variable representation will also be presented. Students will learn the conceptual and mathematical underpinnings of the equations that describe random movement in arbitrary dimensions and arbitrary topologies. Through lots of exercises during the lectures and as coursework in between lectures, students will have plenty of opportunities for a hands-on experience.
Course Outcomes:
- Understanding of fundamental transport concepts in statistical physics from diffusion and correlated movement to first-passage phenomena
- Ability to model random walk movement and basic interaction processes such as trapping, encounters, exclusion
- Ability to quantify the so-called first-passage, first-encounter and first-absorption processes
- Ability to represent the random walk dynamics in a heterogeneous environment
Intended Audience / Pre-requisites:
Undergraduate/Postgraduate students and Faculty with prior experience in linear algebra and calculus. Familiarity with probability concepts is helpful, but not required
Materials such as published papers and solved exercises will be made digitally available
