  2. 1. Homogenization of some elliptic equations with connections to elasticity

    Author : Klas Pettersson; Patrizia Donato; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik; Mathematics; Matematik;

    Abstract : In this PhD thesis we prove some properties of elliptic equations in connection with periodic homogenization. We mainly study the stationary linearized elasticity system. This thesis consists of five papers complemented with a short introduction.The first paper concerns some elliptic equations on a domain with oscillating boundary. READ MORE

  4. 2. Boundary Value Problems for Nonlinear Elliptic Equations in Divergence Form

    Author : Abubakar Mwasa; Jana Björn; Anders Björn; Tomas Sjödin; Sorina Barza; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The thesis consists of three papers focussing on the study of nonlinear elliptic partial differential equations in a nonempty open subset Ω of the n-dimensional Euclidean space Rn. We study the existence and uniqueness of the solutions, as well as their behaviour near the boundary of Ω. READ MORE

  5. 3. On Steady Water Waves and Their Properties

    Author : Mats Ehrnström; Matematik (naturvetenskapliga fakulteten); []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Particle trajectories; Water waves; Vorticity; Maximum principles; Elliptic equations;

    Abstract : Abstract: This thesis consists of four papers related to various aspects of steady water waves. Paper I: Deep-water waves with vorticity: symmetry and rotational behaviour. We show that for steady, periodic, and rotational gravity deep-water waves, a monotone surface profile between troughs and crests implies symmetry. READ MORE
