  3. 2. Death and the Self : A Metaphysical Investigation of the Rationality of Afterlife Beliefs in the Contemporary Intellectual Climate

    Författare :Johan Eddebo; Mikael Stenmark; Karin Johanneson; Charles Taliaferro; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; death; subjectivity; selfhood; afterlife; irreducibility; critique of naturalism; immaterialist ontologies; dualism; idealism; philosophy of religion; quantum theory; interpretations of quantum mechanics; modernity; Philosophy of Religion; Religionsfilosofi;

    Sammanfattning : This dissertation's purpose is to test the hypothesis that beliefs in the possibility of post-mortem survival can be rationally held within the context of the contemporary scientific and philosophical environment. In terms of criteria of rationality, a basic evidentialism is assumed, such that propositions which are sufficiently supported by the available evidence can be rationally held.

  4. 3. Decomposition of perverse sheaves

    Författare :Iara Cristina Alvarinho Gonçalves; Rikard Bögvad; Nero Budur; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sheaf cohomology; hyperplane arrangements; D-modules; Mathematics; matematik;

    Sammanfattning : This PhD thesis consists in three papers in which we describe irreducibility conditions and the number of factors in a composition series of certain perverse sheaves. We study some particular cases, providing examples and showing how to explicitly use perverse sheaves to obtain precise results. LÄS MER

  5. 4. On eigenvalues of the Schrödinger operator with a complex-valued polynomial potential

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; schroedinger; even spectral determinant polynomial potential eigenvalue; Mathematical analysis; Analys; Mathematics; matematik;

    Sammanfattning : In this thesis, we generalize a recent result of A. Eremenko and A. Gabrielov on irreducibility of the spectral discriminant for the Schroedinger equation with quartic potentials. LÄS MER

  7. 5. Building and Destroying Urns, Graphs, and Trees

    Författare :Fabian Burghart; Cecilia Holmgren; Svante Janson; Klas Markström; Uppsala universitet; []

    Sammanfattning : In this thesis, consisting of an introduction and four papers, different models in the mathematical area of combinatorial probability are investigated.In Paper I, two operations for combining generalised Pólya urns, called disjoint union and product, are defined. LÄS MER
