Lefschetz zeta function

The Lefschetz zeta function is a mathematical tool used in the field of algebraic topology and dynamical systems to study the properties of continuous maps on topological spaces. It provides a way to encode information about the fixed points of a map and their behavior. Given a continuous map \( f \) from a topological space \( X \) to itself, one can consider the number of fixed points of iterates of this map.
