Presented by:

Venue:

Abstract: 
Nature abounds with examples of stochastic processes, from scattering in porous media to fluctuations in neuronal signalling. Moving into a more abstract realm, we encounter Lévy processes in probabilistic theory and finance.
We will discuss the breadth of examples which can be studied under the lens of stochastic processes, with a focus on random walks. Further, we will illustrate the scope and application of Wiener-Hopf factorisation to these problems by the calculation of a first passage time quantity in a simplified model.
