摘要：

We study the parabolic Anderson model in (1 + 1) dimensions with nearest neighbor jumps and space time white noise (discrete space/continuous time). We prove a contour integral formula for the second moment and compute the second moment Lyapunov exponent. For the model with only jumps to the right, we prove a contour integral formula for all moments and compute moment Lyapunov exponents of all orders.
