In this paper, we define the transformations of Newton and prove some properties related to them. We did a study on elliptic operator and use it to prove that given some conditions for the sectional curvature of a riemannian manifold M,able function of increasing height (in modulus) of a graph vertical compact immersed in MXR.Neste trabalho, definimos as transformações de Newton e provamos algumas propriedades relacionadas a elas. Fizemos um estudo sobre operador elíptico e usamos isso para provar que dadas algumas condições para a curvatura seccional de uma variedade riemanniana M, conseguimos majorar a função altura (em modulo) de um gráfico vertical compacto imerso em MxR
