# Random Walks, First Returns and Sparre Andersen Theorem

#### Random Walks, First Returns and Sparre Andersen Theorem

- Event time: 11:30am
- Event date: 27th April 2016
- Speaker: Professor Martin Evans (School of Physics & Astronomy, University of Edinburgh)
- Location: Room 2511, James Clerk Maxwell Building (JCMB) James Clerk Maxwell Building Peter Guthrie Tait Road Edinburgh EH9 3FD GB

### Event details

In this talk I'll look at computing the probability of the time to the first return to the origin of a random walk. I'll consider various jump distributions of the walk and discuss (without proof) a very strong result known as Sparre Andersen Theorem.
