  2. 1. BV-algebras in topology and homotopy algebra

    Author : Kaj Börjeson; Alexander Berglund; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; matematik;

    Abstract : This Licentiate thesis consists of two papers. The first paper is called A-infinity-algebras derived from associative algebras with a non-derivation differential. The second paper is joint work with A. Berglund and is called Free loop space homology of highly connected manifolds. READ MORE

  4. 2. Free loop spaces, Koszul duality and A-infinity algebras

    Author : Kaj Börjeson; Alexander Berglund; Pascal Lambrechts; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Koszul duality; free loop spaces; a-infinity algebras; BV-algebras; string topology; Mathematics; matematik;

    Abstract : This thesis consists of four papers on the topics of free loop spaces, Koszul duality and A∞-algebras. In Paper I we consider a definition of differential operators for noncommutative algebras. This definition is inspired by the connections between differential operators of commutative algebras, L∞-algebras and BV-algebras. READ MORE

  5. 3. BRST and Topological Gauge Theories

    Author : Niclas Sandström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gauge theory; BRST-quantization; topological field theory; BV-quantization; almost product structure APS ; superfield formulation;

    Abstract : In this thesis, the BRST-quantization of gauge theories is discussed. A detailed analysis of the BRST-quantization on inner product spaces is performed for a class of abelian models, including reparametrization invariant ones. General rules how to obtain physical wave functions and propagators are proposed. READ MORE

  6. 4. Vaginal commensal bacteria. Interactions with cervix epithelial and monocytic cells and influence on cytokines and secretory leukocyte protease inhibitor, SLPI

    Author : Louise Strömbeck; Göteborgs universitet; []
    Keywords : Prevotella bivia; bacterial vaginosis BV ; invasion; Lactobacillus; secretory leukocyte protease inhibitor SLPI ; cytokines; THP-1; HeLa cells;

    Abstract : Vaginal commensal bacteria Interactions with cervix epithelial and monocytic cells and influence on cytokines and secretory leukocyte protease inhibitor, SLPI Louise Strömbeck Department of Infectious Medicine, Gothenburg University Abstract Lactobacillus is the predominant species of the vaginal microbiota in women of childbearing age. Lactobacilli are thought to contribute to the local immune defence by producing a variety of antimicrobial substances and, thereby, attenuate growth of other opportunistic bacteria. READ MORE

  7. 5. Amines and Bacterial Vaginosis

    Author : Helen Wolrath; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Bacterial Vaginosis (BY) is a common syndrome, with a prevalence of 10-30% in women of childbearing age. The decisive pathogenetic factoris thought to have a microbiological origin, but so far no specific bacteria have been implicated in causing BV. READ MORE
