Moments and Lyapunov exponents for the parabolic Anderson model
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...
