Abstract
We study the asymptotic behavior for large N of the disconnection time T N of simple random walk on the discrete cylinder (ℤ/Nℤ)d×ℤ. When d is sufficiently large, we are able to substantially improve the lower bounds on T N previously derived in [3], for d≥2. We show here that the laws of N 2d /T N are tight.
