1. 1. Twisting it up the Quantum Way : On Matrix Models, q-deformations and Supersymmetric Gauge Theories

   Författare :Rebecca Lodin; Maxim Zabzine; Taro Kimura; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matrix models; Virasoro constraints; Virasoro algebra; W algebra; q-deformations; Supersymmetric gauge theories; Theoretical Physics; Teoretisk fysik;

   Sammanfattning : The mathematical framework which quantum field theory constitutes has been very successful in describing nature. As an extension of such a framework, the idea of supersymmetry was introduced. This greatly simplified the mathematical description of the theories, making them more tractable. LÄS MER

   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
