  1. 1. BRST and Topological Gauge Theories

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

    Sammanfattning : 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. LÄS MER

  3. 2. Small-scale multilingualism and language contact in egalitarian foragers

    Författare :Joanne Yager; Allmän språkvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; small-scale multilingualism; egalitarian language contact; egalitarian bilingualism; bilingual semantic interaction; crosslinguistic influence; lexical convergence; bilingual optimization strategies; Aslian; Austroasiatic; Jedek; Jahai; foragers; undiscovered languages; topological relations; caused motion events; reciprocal events; phylogenetic networks; small-scale multilingualism; egalitarian language contact; egalitarian bilingualism; bilingual semantic interaction; crosslinguistic influence; lexical convergence; bilingual optimization strategies; Aslian; Austroasiatic; Jedek; Jahai; foragers; undiscovered languages; topological relations; caused motion events; reciprocal events; phylogenetic networks;

    Sammanfattning : Situations of multilingualism and language contact in which language varieties are small in scale and relatively equal in social status are important phenomena affecting processes of language change throughout human history. Despite this, our knowledge about the outcomes of multilingualism and language contact in this kind of setting remains limited. LÄS MER

  5. 4. Holonomy in Quantum Information Geometry

    Författare :Ole Andersson; Ingemar Bengtsson; Boris Shapiro; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik; Physics;

    Sammanfattning : In this thesis we provide a uniform treatment of the two most popular non-adiabatic geometric phases for dynamical systems of mixed quantum states, namely those of Uhlmann and of Sjöqvist et al. We develop a holonomy theory for the latter which we also relate to the already existing theory for the former. LÄS MER

  7. 5. Automatic generation of a view to geographical database

    Författare :Mats Dunkars; KTH; []
    Nyckelord :Digital cartography; automatic cartographic generalization; object oriented modeling;

    Sammanfattning : This thesis concerns object oriented modelling and automatic generalisation of geographic information. The focus however is not on traditional paper maps, but on screen maps that are automatically generated from a geographical database. LÄS MER
