The supercooled dynamics of a Lennard-Jones model liquid is numericallyinvestigated studying relevant points of the potential energy surface, i.e. theminima of the square gradient of total potential energy $V$. The main findingsare: ({\it i}) the number of negative curvatures $n$ of these sampled pointsappears to extrapolate to zero at the mode coupling critical temperature $T_c$;({\it ii}) the temperature behavior of $n(T)$ has a close relationship with thetemperature behavior of the diffusivity; ({\it iii}) the potential energylandscape shows an high regularity in the distances among the relevant pointsand in their energy location. Finally we discuss a model of the landscape,previously introduced by Madan and Keyes [J. Chem. Phys. {\bf 98}, 3342(1993)], able to reproduce the previous findings.Comment: To be published in J. Chem. Phy
