  "abstract": "We study the lepton flavor violating (LFV) processes $l_{i}\\longrightarrow l_{j}\\nu_{l}\\bar{\\nu}_{l}$ in the context of the topcolor-assisted technicolor (TC2) models. We find that the branching ratios $B_{r}(\\tau\\longrightarrow l_{j}\\nu_{\\tau}\\bar{\\nu}_{\\tau})$ are larger than the branching ratios $B_{r}(\\tau\\longrightarrow l_{j}\\nu_{l}\\bar{\\nu}_{l})$ in all of the parameter space. Over a wide range of parameter space, we have $B_{r}(\\tau\\longrightarrow l_{j}\\nu_{\\tau}\\bar{\\nu}_{\\tau})\\sim 10^{-6}$ and $B_{r}(\\tau\\longrightarrow l_{j}\\nu_{l}\\bar{\\nu}_{l})\\sim 10^{-9} (l=\\mu$ or $e)$. Taking into account the bounds given by the experimental upper limit $Br^{exp}(\\mu\\longrightarrow3e)\\leq1\\times10^{-12}$ on the free parameters of TC2 models, we further give the upper limits of the LFV processes $l_{i}\\longrightarrow l_{j}\\nu_{l}\\bar{\\nu}_{l}$. We hope that the results may be useful to partly explain the data of the neutrino oscillations and the future neutrino experimental data might be used to test TC2 models.",
