1. Approximating extrema of quadratic forms using Krylov subspaces
University essay from Lunds universitet/Matematik LTHAbstract : In this thesis approximations to quadratic forms using Krylov subspaces are presented. These quantities are approximations of the norm and logarithmic norm of a matrix. In order to find these quantities an eigenvalue problem has to be solved, but because of limited storage and time, this is not feasible in practice with large matrices. READ MORE

2. The Loewner Equation: An introduction and the winding of its trace
University essay from KTH/Matematik (Avd.)Abstract : In the early 1920's Karl Löwner (later Charles Loewner) introduced a simple differential equation that encodes domains in the complex plane changing continuously in time t into a real-valued function of t. This thesis centers around this equation, called the Loewner Equation, and has three separate parts. READ MORE
