Abstract: 

A multi-particle generalization of edge-reinforced random walk (ERRW) is introduced. We observe that in multi-particle case, most of the ERRW techniques do not work: no Polya urn representation on acyclic graphs, no partial exchangeability. The recurrence of a two-point edge-reinforced process on a one-dimensional lattice is proved.
