Abstract

We consider the generalized Anderson Model Δ+nNωnPn\Delta+\sum_{n\in\mathcal{N}}\omega_n P_n, where N\mathcal{N} is a countable set, {ωn}nN\{\omega_n\}_{n\in\mathcal{N}} are i.i.d random variables and PnP_n are rank N<N<\infty projections. For these models we prove theorem analogous to that of Jak\v{s}i\'{c}-Last on the equivalence of the trace measure σn()=tr(PnEHω()Pn)\sigma_n(\cdot)=tr(P_nE_{H^\omega}(\cdot)P_n) for nNn\in\mathcal{N} a.e ω\omega. Our model covers the dimer and polymer models.
