Hidden dynamical zeta functions

Abstract: I will discuss examples of a phenomenon first observed (to my knowledge) by Yash Puri. Certain - as it turns out, many - sequences that arise naturally in combinatorics or number theory fail to count periodic points (that is, be the coefficients of a dynamical zeta function) but succeed after some modest modification. Examples include the Stirling numbers and linear recurrence sequences.
