On the Second-Degree Exterior Derivation of Kahler Modules on X circle times Y

This article presents a new approach to stress the properties of Kahler modules. In this paper, we construct the Kahler modules of second-degree exterior derivations and we constitute an exact sequence of X circle times Y-modules. Particularly, we examine Kahler modules on X circle times Y, and search for the homological size of Lambda(2)(Omega(1) (X circle times Y)
