Human Sexual Contact Network as a Bipartite Graph
Abstract
A simple model to encapsulate the essential growth properties of the web of human sexual contacts is presented. In the model only heterosexual connection is considered and represented by a random growing bipartite graph where both male-female contact networks grow simultaneously. The time evolution of the model is analysed by a rate equation approach leading to confirm that male and female sexual contact distributions decay as power laws with exponents depending on influx and charisma of the sexes.
