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

    Author : Johan Eddebo; Mikael Stenmark; Karin Johanneson; Charles Taliaferro; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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.

  5. 3. Decomposition of perverse sheaves

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

    Abstract : 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. READ MORE

    Abstract : 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. READ MORE

  7. 5. On Aggregation and Dynamics of Opinions in Complex Networks

    Author : Olle Abrahamsson; Erik G. Larsson; Danyo Danev; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis studies two problems defined on complex networks, of which the first explores a conceivable extension of structural balance theory and the other concerns convergence issues in opinion dynamics. In the first half of the thesis we discuss possible definitions of structural balance conditions in a network with preference orderings as node attributes.
