摘要：
We consider alloy type random Schrodinger operators on a cubic lattice whose randomness is generated by the sign-indefinite single-site potential. We derive Anderson localization for this class of models in the Lifshitz tails regime, i.e. when the coupling parameter lambda is small, for the energies Ea parts per thousand currency signa'C lambda (2).
