Abstract: 

In this talk we'll consider Branching Brownian Motion with two absorbing boundaries as a model for a binary-reproducing, non-motile population's response to a changing environment. This will be done via certain martingale changes of measure, using a "distinguished path" technique. These methods suggest the possibility of a simple proof of Kesten's famous critical parameter values for BBM with one absorbing boundary, and this area of active research is discussed briefly.

The talk will be, in part, an introduction to the methods of distinguished path analysis, and will emphasize general understanding over technical details.
