  3. 2. Reiterated homogenization and G-convergence for some sequences of monotone operators

    Författare :Marianne Olsson; Mårten Gulliksson; Anders Holmbom; Nils Svanstedt; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Homogenization; G-convergence; Multiple scales; Monotone operators; MATHEMATICS; MATEMATIK;

    Sammanfattning : In this thesis, the main focus is on G-convergence and homogenization of monotone parabolic equations with multiple scales. This kind of equation is examined with respect to existence and uniqueness of the solution, in view of the properties of some monotone operators. LÄS MER

  7. 5. Homogenization theory for structures of honeycomb and chessboard types

    Författare :Simula Leon; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : This thesis consists of 5 papers. The first paper starts with an introduction to some of the most fundamental mathematical theory connected to homogenization. In particular, a portion of the classical theory in homogenization is presented, such as the convergence of monotone operators and homogenization in random domains. LÄS MER
