We will use this technique to calculate the first derivative of the simple eigenvalue of Laplace operator with respect to the domain. Then we show the technique developed by Marcos Montenegro and Julian Haddad in 2015 to calculate the derivative of simple eigenvalues of uniformly elliptical operators of second order in non-regular domains, with respect to the coefficients of the operator and the domain, where they are taken Non-regular disturbances of the problem definition domain. Finally, we highlight some differences and similarities between both techniques. / Neste trabalho apresentamos o cálculo diferencial de domínios, desenvolvido por Daniel Henry em 2005, aplicado em problemas de pertubação de fronteira de domínio regular. Ultilizaremos essa técnica para calcular a primeira derivada do autovalor simples do Laplaciano com respeito ao domínio. Em seguida, exibimos a técnica desenvolvida por Marcos Montenegro e Julian Haddad em 2015 para calcular a derivada de autovalores simples de operadores uniformemente elípticos de segunda ordem em domínios não-regulares, com respeito aos coeficientes do operador e ao domínio, onde são tomadas perturbações não regulares do domínio de definição do problema. Por fim, destacamos algumas diferenças e semelhanças entre ambas as técnicas.
