What is a dynamical zeta function?

Sometimes, when one has very smart coauthors, certain theorems appear in one's papers which one has apparently helped prove, but which one does not understand. Sometimes, these statements say things about zeta functions. Being but a humble geometer and dynamicist, sometimes one feels a certain embarrassment having one's name attached to such august mathematical objects. In such a situation, one sometimes feels compelled to try to understand these objects and why they are being used to study dynamics.

On a completely unrelated note, in this talk I'll give a survey of a number of different types of zeta functions which are defined in analogy with number-theoretic zeta functions, and which can all be cast in a common framework as dynamical zeta functions. I'll discuss what these functions are, what properties we want them to have, and what sort of statements these properties imply. I'll discuss zeta functions for graphs, hyperbolic manifolds, and general dynamical systems, and even note an application involving knot theory.
