It follows that a positive function is log-convex in the Jensen sense if and only if it is 2-exponentially convex in the Jensen sense.
Contributors here take the task on, with papers on such aspects as the maximal characterization of Hardy-Sobolev spaces on manifolds, approximately Gaussian marginals and the hyperplane conjecture, on the existence of sub-Gaussian directions for log-concave measures, isoperimetric bounds on convex manifolds, and the log-convex density conjecture.
We note that 0-convex function is simply log-convex function and 1-convex function is ordinary convex function.
