The 2011

**Birnbaum Lecture in Probability will be delivered by Steven Evans (University of California, Berkeley).**

Two needles in exponential haystacks

**Circular Distributions and Fisheries Models**On Friday October 14, 2011, we are holding the Pacific Northwest Seminar in honour of Dr. Bill Reed who retired from the University of Victoria on July 1, 2011. The seminars will focus on two areas that Bill has worked in: assessing goodness-of-fit and applied statistics. Michael Stephens will offer a theoretical discussion of assessing the fit of circular distributions and emerging issues in this field. Jon Schnute will discuss applied fisheries models and will look at what further research is required in this area.

The Langevin process and the trace formula.

Buffon's needle probability for rational product Cantor sets

The content of the course will be based on the interests and expertise of the participants. Topics of 3-lecture series will include, but be in no sense limited to:

1. Bousfield Localization and Axiomatic Stable Homotopy Categories

2. Moduli Spaces of Riemann Surfaces

3. Transfer in Stable Homotopy Theory

4. Ring Spectra

combinatorics, algebraic topology, algebraic geometry, and applications
