    Abstract : This thesis deals with relativistic membranes and, in particular, a limit called stretched membranes. The thesis also considers the relation of membranes to the conjectured M-theory and string theory. The thesis is divided into two parts. One introductory part where I introduce areas which are of relevance for the second part. READ MORE

  5. 3. Strings, Branes and Non-trivial Space-times

    Abstract : This thesis deals with different aspects of string and /p/-brane theories. One of the motivations for string theory is to unify the forces in nature and produce a quantum theory of gravity. /p/-branes and related objects arise in string theory and are related to a non-perturbative definition of the theory.

  6. 4. Mistaken morality? : an essay on moral error theory

    Author : Emma Beckman; Gunnar Björnsson; Bart Streumer; Umeå universitet; []
    Keywords : HUMANIORA; HUMANITIES; moral error theory; Mackie; Joyce; Olson; normative institution; fictionalism; normative error theory; epistemic error theory; irreducible normativity; abolitionism; conservationism; propagandism;

    Abstract : This dissertation explores arguments and questions related to moral error theory – the idea that morality inevitably involves a fundamental and serious error such that moral judgments and statements never come out true. It is suggested that the truth of error theory remains a non-negligible possibility, and that we for this reason should take a version of moral fictionalism seriously. READ MORE
