    Discrete and finite Genral Relativity

    Full text link
    We develop the General Theory of Relativity in a formalism with extended causality that describes physical interaction through discrete, transversal and localized pointlike fields. The homogeneous field equations are then solved for a finite, singularity-free, point-like field that we associate to a ``classical graviton". The standard Einstein's continuous formalism is retrieved by means of an averaging process, and its continuous solutions are determined by the chosen imposed symetry. The Schwarzschild metric is obtained by the imposition of spherical symmetry on the averaged field.Comment: Modified conform the version to appear in Classical and Quantum Gravit

    TCC (graduação) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Curso de Graduação em Língua e Literatura Estrangeira.RESUMO: Existencialismo é uma doutrina filosófica focada no ser humano em face da realidade, que vem atraindo muitos escritores há décadas. Muitos estudiosos vêm discutindo a possibilidade de Saul Bellow poder ser considerado um escritor Existencialista. A presente pesquisa analisa o livro do autor Estadunidense Seize the Day através de uma revisão bibliográfica. Aplicando os pressupostos defendidos por Jean-Paul Sartre ao livro foi possível encontrar conexões com o que defende o pensador Francês, embora falte certa densidade ao livro de Bellow quando comparado aos de outros trabalhos Existencialistas.ABSTRACT: Existentialism is a philophical doctrine focused on the human being inface of reality that has been attracting many writers for decades. Many scholars have been discussing the Existentialism in Saul Bellow's production. This work analysis the American author's novel Seize the Day through a bibliographical review. Applying presupposes defended by Jean-Paul Sartre to the novel it was possible to find connections with the French thinker's ideas though the novel lacks some density when compared to other Existentialist works
