Abstract

A notion of entropy is introduced for causal fermion systems. This entropy is a measure of the state of disorder of a causal fermion system at a given time compared to the vacuum. The definition is given both in the finite- and infinite-dimensional settings. General properties of the entropy are analyzed.
