1. 1. Institutional fragmentation and social service variations : A Scandinavian comparison

   Författare :Dietmar Rauch; Stefan Svallfors; Jonas Edlund; Olli Kangas; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociology; Sociologi;

   Sammanfattning : The Scandinavian welfare states – Denmark, Norway, and Sweden – are usually assumed to constitute a coherent and unique social service model, characterized among other things by a high level of universalism. This thesis questions the existence of such a model. LÄS MER

3. 2. Exactly solved quantum many-body systems in one dimension

   Författare :Martin Hallnäs; Edwin Langmann; Stefan Rauch-Wojciechowski; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Sammanfattning : This thesis is devoted to the study of various examples of exactly solved quantum many-body systems in one-dimension. It is divided into two parts: the first provides background and complementary results to the second, which consists of three scientific papers. LÄS MER

4. 3. Systems of Linear First Order Partial Differential Equations Admitting a Bilinear Multiplication of Solutions

   Författare :Jens Jonasson; Stefan Rauch; Sergio Benenti; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cauchy–Riemann equations; holomorphic functions; algebra; MATHEMATICS; MATEMATIK;

   Sammanfattning : The Cauchy–Riemann equations admit a bilinear multiplication of solutions, since the product of two holomorphic functions is again holomorphic. This multiplication plays the role of a nonlinear superposition principle for solutions, allowing for construction of new solutions from already known ones, and it leads to the exceptional property of the Cauchy–Riemann equations that all solutions can locally be built from power series of a single solution z = x + iy ∈ C.

5. 4. New Phenomena in the World of Peaked Solitons

   Författare :Marcus Kardell; Hans Lundmark; Stefan Rauch; Joakim Arnlind; Jonatan Lenells; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The aim of this work is to present new contributions to the theory of peaked solitons. The thesis consists of two papers,which are named “Newsolutionswith peakon creation in the Camassa–HolmandNovikov equations” and “Peakon-antipeakon solutions of the Novikov equation” respectively.

7. 5. Analysis of Dynamics of the Tippe Top

   Författare :Nils Rutstam; Stefan Rauch; Hans Lundmark; Tudor Ratiu; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The Tippe Top is a toy that has the form of a truncated sphere with a small peg. When spun on its spherical part on a flat supporting surface it will start to turn upside down to spin on its peg. LÄS MER
