Geometry of Departmental Discussions
You know what happens; you bring to the department a wellthought
out proposal only to have some group "improve it."
In using elementary geometry to explain why we must expect this
annoying behavior, I also indicate why this phenomenon, and
related issues, involve an interesting variety of mathematics
ranging from game theory to singularity theory.

Developing a Qualitative Evolutionary
Game Theory
In recent years, evolutionary game theory has been developed
to analyze issues of dynamics for areas ranging from ecology
and evolutionary biology to the social and behavioral sciences.
But there are problems: first, the difficult mathematics limits
what we can do. Second, because we really do not understand
what dynamics is appropriate for many of these settings, we
run the risk of working hard to make precise statements about
equations that nobody believes. To avoid these and other difficulties,
a "qualitative" evolutionary game theory is being
developed. I will introduce the basic ideas.
