*Speaker: Tomasz Gubiec *

*Abstract: * *Over 50 years ago, two physicists Montroll and Weiss in the physical context of dispersive transport and diffusion introduced stochastic process, named Continuous-Time Random Walk (CTRW). The trajectory of such a process is created by elementary events ‘spatial’ jumps of the stochastic process preceded by waiting (or interevent or pausing) time. Since introduction, CTRW found innumerable application in different fields [1]. In this seminar, I will focus on the application of CTRW to finance [2] and I will tell the story of how this application turned out to be fruitful for both sided and motivated new directions of research [3,4].*
