# Non-linear Fisher travelling waves and boundary effects : the survival probability of a population of branching random walks

#### Non-linear Fisher travelling waves and boundary effects : the survival probability of a population of branching random walks

- Event time: 3:00pm
- Event date: 9th July 2009
- Speaker: Damien Simon (University of Edinburgh)
- Location: Room 4309, James Clerk Maxwell Building (JCMB) James Clerk Maxwell Building Peter Guthrie Tait Road Edinburgh EH9 3FD GB

### Event details

In this second talk, I will show an exact duality between Fisher travelling waves and branching random walks. I will then use it to study the transition to extinction of branching random walks in presence of absorbing boundaries and show how the essential singularities can be described.
