Resolubilidade contínua e singularidades removíveis para a equação divergente

Abstract

In this text we study some results obtained by Nguyen Cong Phuc and Monica Torres in the paper "Characterizations of the Existence and Removable Singularities of Divergence-measure Vector Fields" regarding the characterisation of solutions and removable singularities of the equation div F = u, where u is a measure and F is a continuous or Lp vector field. To perform this study, the text presents definitions and properties on divergence-measure vector fields, Hausdorff measures, Sobolev capacity and functions of bounded variation.
