Théorème de Stokes Et Intégration Sur Les Courants Entiers

Résumé du livre

Methods of gauge integration, like those developped by W. F. Pfeffer on bounded sets of finite perimeter, are well suited to the study of integration theorems, such as the Fundamental Theorem of Calculus, The Divergence Theorem and Stokes' Theorem. In this thesis, Pfeffer Integration is transposed to the context of integral currents in the sense of Federer and Fleming. Not all integral currents are adapted to this type of gauge integration and a criterion on the singular set of the current is obtained. Well behaved currents include all 1-dimensional integral currents, integral currents definable in an o-minimal structure and mass minimizing integral currents whenever the boundary singularities are controlled. All those currents are shown to satisfy a general Stokes' Theorem. On the other hand, an example is given of an integral current of dimension 2 in R3 with only one singular point, which does not satisfy such a general Stokes-Cartan Theorem. This thesis also contains the definitions of non-absolutely convergent integrations methods on 1-dimensionalintegral currents as well as on integral currents of any dimension in Euclidean space, whenever their singular set has controlled relative Minkowski content.
