Este trabalho desenvolve a demonstração, dada por Wang em 1977, para a conjectura de Sally, enunciada em 1983, que diz que dado um anel local noetheriano Cohen-Macaulay de dimensão d e dimensão de imersão e + d - 2, onde e é a sua multiplicidade, seu anel graduado associado possui profundidade maior ou igual a d - 1. Utilizando uma propriedade demonstrada por Sally em 1979 (Sally Machine), reduzimos o problema ao caso em que a dimensão do anel é 2, e assim, demonstramos que a profundidade do anel graduado associado é positiva. / This work develops the proof, given by Wang in 1977, for Sally's conjecture, stated in 1983. The conjecture says that given a local Noetherian Cohen-Macaulay ring of dimension d and embedding dimension e + d - 2, where e is its multiplicity, its associated graded ring has depth greater than or equal to d - 1. Using a property proved by Sally, in 1979, called the Sally Machine, we reduce the problem to the 2-dimensional case proving that the depth of its associated graded ring is positive.

Wells Oliver, a mathematician, and his partner Malin move to Kythera, a remote Greek island, from Canada and Sweden, their respective countries of origin. In doing so, they hope to transform their lives in a way that will allow them to focus on their budding love affair, but they are also running away from obligations and people they are trying to leave behind. On Kythera, they realize that even in the most distant locales, the past is never far below the surface.
