Abstract
In this paper, the axiomatic steps leading to the entropy of doubly stochastic operators are localized. This results in a map which is indeed a local entropy map for doubly stochastic operators. Some of the properties of the introduced local quantities are also studied and compared to the corresponding steps in the axiomatic approach.
