Abstract

We introduce the multivariate analogue of the well known inequality 1+xex1+x\leq \mathrm{e}^x, for an abstract non negative real number xx. The result emerges from the study of the blow up time of certain solutions of the Cauchy problem for a particular ODE. It is also closely related to the notion of completely monotone functions and the theory of divided differences.
