Abstract

As the title indicates this paper will describe several extensions and applications of the Γ\Gamma2 integrated criterion introduced by M. Ledoux following ideas of B. Hellffer. We introduce general weak versions and show that they are equivalent to the weak Poincar{\'e} inequalities introduced by M. R{\"o}ckner and F. Y. Wang. We also discuss special weak versions appropriate to the study of log-concave measures and log-concave perturbations of product measures.
