We prove that for a sequence of finite vertex-transitive graphs of increasing sizes, the cover times are asymptotically concentrated if and only if the product of the spectral-gap and the expected cover time diverges. In fact, we prove this for general reversible Markov chains under the much weaker assumption (than transitivity) that the maximal hitting time of a state is of the same order as the average hitting time.

    For reversible finite Markov chains, the L-infinity mixing time is at most trel log(e thit / trel), so the mixing time is comparable to the maximal hitting time exactly when the spectral gap times the hitting time rem...
