  1. 1. Immigrant entrepreneurs in a changing institutional context : a mixed embeddedness approach

    Author : Aliaksei Kazlou; Martin Klinthäll; Susanne Urban; Karl Wennberg; Monder Ram; Linköpings universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Immigrant entrepreneurs; Mixed embeddedness; Entrepreneurial process; Institutional change; Invandrarföretagare; Mixed embeddedness; Entreprenörsprocess; Institutionell förändring;

    Abstract : Immigrant entrepreneurs are known to be heterogeneous in terms of available resources and entrepreneurial outcomes. However, this heterogeneity, as well as immigrant entrepreneurs’ embeddedness in social networks and the institutional context of high-income welfare states such as Sweden, remains understudied.

  2. 2. Exploring the Set of Quantum States

    Author : Åsa Ericsson; Ingemar Bengtsson; Christopher Fuchs; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; quantum mechanics; quantum states; density matrices; quantum information; geometry; Physics; Fysik; Theoretical Physics; teoretisk fysik;

    Abstract : Quantum mechanical properties of finite dimensional quantum systems are used within the field of quantum information. In this thesis the set of states (density matrices) for such systems is studied and described, largely in geometrical terms. READ MORE

  3. 3. Embedding Theorems for Mixed Norm Spaces and Applications

    Author : Robert Algervik; Viktor Kolyada; Javier Soria; Karlstads universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; mixed norms; rearrangements; modulus of continuity; embeddings; Sobolev spaces; Besov spaces; Lorentz spaces; Mathematical analysis; Analys; Matematik; Mathematics;

    Abstract : This thesis is devoted to the study of mixed norm spaces that arise in connection with embeddings of Sobolev and Besov type spaces. We study different structural, integrability, and smoothness properties of functions satisfying certain mixed norm conditions. Conditions of this type are determined by the behaviour of linear sections of functions. READ MORE

  4. 4. Embedding Theorems for Mixed Norm Spaces and Applications

    Author : Robert Algervik; Viktor Kolyada; Lars-Erik Persson; Karlstads universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; mixed norms; embeddings; rearrangements; anisotropic fractional Sobolev spaces; anisotropic Besov spaces; mixade normer; inbäddningar; omarrangeringar; anisotropa fractionära Sobolev rum; anisotropa Besov rum; MATHEMATICS; MATEMATIK; Matematik; Mathematics;

    Abstract : This thesis is devoted to the study of mixed norm spaces that arise in connection with embeddings of Sobolev and Besov type spaces. The work in this direction originates in a paper due to Gagliardo (1958), and was continued by Fournier (1988) and by Kolyada (2005). We consider fully anisotropic mixed norm spaces. READ MORE

  5. 5. Geometric and Topological Phases with Applications to Quantum Computation

    Author : Marie Ericsson; Ignacio Cirac; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Physics; geometric phases; topological phases; quantum computation; mixed states; completely positive maps; Fysik; Physics; Fysik; fysik; Physics;

    Abstract : Quantum phenomena related to geometric and topological phases are investigated. The first results presented are theoretical extensions of these phases and related effects. Also experimental proposals to measure some of the described effects are outlined. READ MORE
