1. 1. Aspects of Dimensional Deconstruction and Neutrino Physics

   Författare :Tomas Hällgren; Tommy Ohlsson; Stephan J. Hubber; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dimensional deconstruction; higher-dimensional gauge theories; discretized gravity; neutrino mass; neutrino mixing; neutrino oscillations; Engineering physics; Teknisk fysik;

   Sammanfattning : The existence of at or curved extra spatial dimensions provides new insights into several of the problems which face the Standard Model of particle physics, including the gauge hierarchy problem, the smallness of neutrino masses, and the dark matter problem. However, higher-dimensional gauge theories are not renormalizable and can only be considered as low-energy effective theories, with limited applicability. LÄS MER

3. 2. Spectral/hp Discontinuous Galerkin Methods for Computational Hydraulics

   Sammanfattning : We present the concept of spectral/hp element methods, i.e. finite element methods of arbitrarily (high) polynomial order, and apply the methods to computational hydraulics. LÄS MER
