3. 2. A new method q-calculus

   Författare :Thomas Ernst; Hari M. Srivastava; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; MATEMATIK; MATHEMATICS; MATEMATIK; matematik; Mathematics;

   Sammanfattning : In q-calculus we are looking for q-analogues of mathematical objects, which have the original object as limits when q tends to 1. q-Calculus has wide-ranging applications in analytic number theory and theoretical physics. The main topic of the thesis is the invention of the tilde operator and the renaissance of the q-addition. LÄS MER

4. 3. Multipole moments of axisymmetric spacetimes

   Författare :Thomas Bäckdahl; Magnus Herberthson; Brian Edgar; Kjell Rosquist; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multipole moments; axisymmetry; spacetimes; prescribed; solutions; static; stationary; Kerr; Weyl; Ernst; Theory of relativity; gravitation; Relativitetsteori; gravitation;

   Sammanfattning : In this thesis we study multipole moments of axisymmetric spacetimes. Using the recursive definition of the multipole moments of Geroch and Hansen we develop a method for computing all multipole moments of a stationary axisymmetric spacetime without the use of a recursion.
