In the context of topcolor-assisted techicolor(TC2) models, we study the
contributions of the neutral top-pion Οt0β to the lepton flavor
violating(LFV) processes liββljβΞ³ and liββljβlkβllβ.
We find that the present experimental bound on ΞΌβeΞ³ gives severe
constraints on the free parameters of TC2 models. Taking into account these
constraints, we consider the processes liββljβlkβllβ generated by
top-pion exchange at the tree-level and the one loop level, and obtain
