Precisely, we generalize some classical theorems of the theory of surfaces and unified proof of other results, seemingly unrelated . In addition , we study the existence of holomorphic quadratic differential , high estimates and apply the abstract theory that the classification of surfaces of special Weingarten elliptical , complete and dipped in R³ , whose Gaussian curvature does not change sign. / Neste trabalho, dissertamos sobre uma teoria abstrata para a equação de variedades bidimensionais (ou simplesmente superfícies), a saber, a teoria dos pares de Codazzi, formas espaciais R³, S³ e H³. Precisamente, generalizamos alguns teoremas clássicos da teoria de superfícies e unificamos a prova de outros resultados, aparentemente não relacionados. Além disso, estudamos a existência de diferenciais quadráticas holomorfas, estimativas de altura e aplicamos a referida teoria abstrata na classificação das superfícies de Weingarten especiais elípticas, completas e mergulhadas em R³, cuja curvatura Gaussiana não muda de sinal.
