We give a simple and direct proof of the existence of a spectral gap under some Lyapunov type condition which is satisfied in particular by log-concave probability measures on Rⁿ. The proof is based on arguments introduced in Bakry and al, but for the sake of completeness, all details are provided.
Bakry et al. (Tue,) studied this question.
