摘要
Diffusion is a common phenomenon in physical, biological or social sciences, but it is not trivial to be analytically described when commodity or information is spread through a social network in our daily life. This work proposed a mathematical model to trace the change of a target attribute under a diffusion mechanism. Such model is applied to a commodity sharing game where participants could donate their tokens to each other in a defined network relationship. The diffusion and decay rates of the model govern respectively the flow directions and magnitude decreases towards the steady state.
