We use several times the Maximum Principle to conclude a Alternating Property of the Dirichlet-to- Neumann map. Using this property, we and that the Kernel satises a given set of inequalities. Finally, we note that these inequalities imply the Alternating Property of the Kernel of the Dirichlet-to-Neumann map. / Neste trabalho dissertamos sobre Propriedades do Funcional de Dirichlet-Neumann para uma equação de condutividade numa variedade diferenciavel bidimensional com bordo. Utilizamos varias vezes o Principio do Maximo para concluir que esse Funcional tem uma Propriedade Alternada. A partir dessa propriedade, verificamos que o Nucleo do Funcional satisfaz um conjunto especifico de desigualdades. Porém, verificamos que essas desigualdades implicam na Propriedade Alternada do Nucleo do Funcional.
