Analyticity of differentiable functions almost everywhere

This work is based on the article Analyticity Of Almost Everywhere Differentiable Functions, it will develop a partitioning lemma for superadditive set functions which will lead to a simple alternative proof of Besicovitch’s theorems.Esse trabalho é baseado no artigo Analyticity Of Almost Everywhere Differentiable Functions, nele desenvolveremos um lema de partição para funções superaditivas que permitirá uma demonstração alternativa e simples dos teoremas de Besicovitch
