  1. 1. A study of the s-step biconjugate gradient method

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Author : Carlotta Boi; [2022]
    Keywords : biconjugate gradient methods; s-step biconjugate gradient methods; nonsymmetric linear systems; sparse matrices.; Mathematics and Statistics;

    Abstract : In this thesis we will examine how to solve linear systems using the s-step biconjugate gradient algorithm, which is an iterative method based on the Krylov subspaces. It is useful especially when we have a large and sparse matrix. READ MORE

  3. 2. Computation of Stationary States for Rotating Bose-Einstein Condensates using Spectral Methods

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Adam Erlandsson; Paul Hedvall; [2020]
    Keywords : ;

    Abstract : The Bose-Einstein condensate is a phase of matter that arises when cooling gases of bosons to extremely low temperatures. When studying these condensates one may use the Gross-Pitaevskii equation, which is a non-linear variant of the Schrödinger equation. READ MORE
