1. Quasi-Lie Algebras and Quasi-Deformations. Algebraic Structures Associated with Twisted Derivations
Sammanfattning : This thesis introduces a new deformation scheme for Lie algebras, which we refer to as ?quasi-deformations? to clearly distinguish it from the classical Grothendieck-Schlessinger and Gers-tenhaber deformation schemes. The main difference is that quasi-deformations are not in gene-ral category-preserving, i.e. LÄS MER
2. Varför blev det (bara) en? : En studie av en offentlig marknad i förändring
Sammanfattning : De senaste två decennierna har forskare i Sverige och andra länder riktat allt större intresse mot offentliga marknader. Sådana organisatoriska arrangemang skapas runtom i svenska kommuner. Den här studien är en longitudinell studie av en process där en offentlig marknad för grundskoleutbildning skapas och utvecklas i en svensk kommun. LÄS MER
3. Control of Quasi-Equivalence in Virus Capsids
Sammanfattning : Many T=3 plant and insect viruses use a molecular switch in form of order/disorder of a segment of the polypeptide chain to regulate the quasi-equivalent contacts. The structure of a mutant of the T=3 capsid of bacteriophage fr confirms that this virus and other members of the Leviviridae family lack a switch mechanism. LÄS MER
4. Sobolev-Type Spaces : Properties of Newtonian Functions Based on Quasi-Banach Function Lattices in Metric Spaces
Sammanfattning : This thesis consists of four papers and focuses on function spaces related to first-order analysis in abstract metric measure spaces. The classical (i.e., Sobolev) theory in Euclidean spaces makes use of summability of distributional gradients, whose definition depends on the linear structure of Rn. LÄS MER
5. Quasi-Phasematched nonlinear processes in KTiOPO4 isomorphs
Sammanfattning : This thesis explores the use of nonlinear crystals from theKTiOPO4(KTP) family with the aim to extend the possibleapplications for laser sources and to gain more knowledge aboutthe materials benefits and limits. The work focussed onoptical parametric oscillators (OPOs) and optical parametricamplifiers (OPAs), which employ second order nonlinearprocesses. LÄS MER
