LFV in semileptonic $\tau$ decays and $\mu -e$ conversion in nuclei in SUSY-seesaw

Here we review the main results of LFV in the semileptonic tau decays $\tau \to \mu PP$($PP = \pi^+ \pi^-, \pi^0 \pi^0, K^+ K^-, K^0 \bar{K}^0$),$\tau \to \mu P$($P = \pi, \eta, \eta^{\prime}$),and$\tau \to \mu V$($V = \rho, \phi$)aswellasin$\mu-e$ conversion in nuclei within SUSY-seesaw scenarios, and compare our predictions with the present experimental bounds
