Abstract: We have studied the contribution of higher order corrections of the flavorsymmetry breaking in the $A 4$ seesaw model with the supersymmetry. Takingaccount of possible higher dimensional mass operators, we predict the deviationfrom the tri-bimaximal lepton mixing for both normal hierarchy and invertedhierarchy of neutrino masses. We have found that the value of $\sin^22\theta {23}$ is larger than 0.96 and the upper bound of $\sin^2\theta {13}$ is0.01. We have also examined the flavor changing neutral current of leptons fromthe soft SUSY breaking in slepton masses and A-terms within the framework ofsupergravity theory. Those magnitudes are enough suppressed to be consistentwith experimental constraints.
