摘要： 

The edge reinforced random walk is a history dependant process, such that the random walker prefers previously visited edges, with a bias proportional to the local time of the edges. In this talk we will gently introduce the subject, present some recent developements, and explain how the idea of fractional moments can be applied to get recurrence in certain regime.  Join with A.
