  1. 1. The Lorenz attractor exists

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Warwick Tucker; Uppsala universitet.; [1998]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; MATEMATIK; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Sammanfattning : We prove that the Lorenz equations support a strange attractor, as conjectured by Edward Lorenz in 1963. We also prove that the attractor is robust, i.e., it persists under small perturbations of the coefficients in the underlying differential equations. LÄS MER

  2. 2. A Numerical Study of the Lorenz and Lorenz-Stenflo Systems

    Detta är en avhandling från Stockholm : KTH

    Författare :Tommy Ekola; KTH.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Warwick Tucker; Strange attractor; Lorenz equations; Lorenz-Stenflo equations; Lorenz attractor; Lorenz-Stenflo attractor; Dynamical systems; Normal form theory; MATEMATIK; MATHEMATICS; MATEMATIK;

    Sammanfattning : In 1998 the Swedish mathematician Warwick Tucker used rigorous interval arithmetic and normal form theory to prove the existence of a strange attractor in the Lorenz system. In large parts, that proof consists of computations implemented and performed on a computer. LÄS MER
