abstract
In this article we start by reviewing some mathematical models for the spread of rumors. We mention some studies carried out using graphs, stochastic and probabilistic models and also some epidemic like and evolutionary models. We analyze a repeated game with the replicator dynamics for the spread of a rumor in a society conformed by an informed population about a rumor that communicates the rumor to another population. The rumor can be communicated in its original form or with the opposite content. We compare the results obtained when only social costs are involved with the case when also communication costs are present.
