  "abstract": "Taking into account the constraints of the present experimental limit of the process $\\mu\\to e\\gamma$ on the free parameters of topcolor-assisted technicolor(TC2) models, we calculate the contributions of the neutral top-pion to the lepton flavor violating(LFV) $Z$ decays $Z\\to l_{i}l_{j}$. Our results show that the value of the branching ratio $Br(Z\\to \\tau l)$ is larger than that of $Br(Z\\to \\mu e)$ in all of the parameter space and there is $Br(Z\\to \\tau\\mu)\\approx Br(Z\\to \\tau e)\\simeq 2\\times 10^{-14} $, which is far from the reach of present or future experiments.",
