  2. 1. Selected Topics in Partial Differential Equations

    Author : Mattias Enstedt; Michael Melgaard; William Desmond Evans; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK; Applied mathematics; Tillämpad matematik;

    Abstract : This Ph.D. thesis consists of five papers and an introduction to the main topics of the thesis. In Paper I we give an abstract criteria for existence of multiple solutions to nonlinear coupled equations involving magnetic Schrödinger operators. READ MORE

  4. 2. To explore and verify in mathematics

    Author : Tomas Bergqvist; Hans Wallin; Johan Lithner; Morten Blomhøj; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Explorations; mathematical reasoning; empirical investigations; graphing calculators; conjectures.; Subject didactics; Ämnesdidaktik; MATHEMATICS; MATEMATIK; didactics of mathematics; matematikdidaktik;

    Abstract : This dissertation consists of four articles and a summary. The main focus of the studies is students' explorations in upper secondary school mathematics. In the first study the central research question was to find out if the students could learn something difficult by using the graphing calculator. READ MORE

  5. 3. Critical point theory with applications to semilinear problems without compactness

    Author : Sara Maad; Jacqueline Fleckinger; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; MATEMATIK; MATHEMATICS; MATEMATIK; Mathematics; Matematik;

    Abstract : The thesis consists of four papers which all regard the study of critical point theory and its applications to boundary value problems of semilinear elliptic equations. More specifically, let Ω be a domain, and consider a boundary value problem of the form -L u + u = f(x,u) in Ω, and with the boundary condition u=0. READ MORE

  6. 4. Comparative Study of Teaching Computational Mathematics in Two Different Learning Environments

    Author : Dara Maghdid; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computational mathematics; Teaching style; Variation Theory; Mathematics values; Motivation;

    Abstract : This thesis aims to investigate necessary adaptations in the design of a mathematics course when it is transferred from one cultural environment to another. We focus on an elementary course in computational mathematics with Python taught at Lund University, Sweden, and at Soran University, Kurdistan/Iraq. This project holds two main parts. READ MORE

  7. 5. Polynomial Hulls and Envelopes of Holomorphy

    Author : Lennart S. Nobel; Burglind Jöricke; Nikolay Shcherbina; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cantor sets; polynomial hulls; envelopes of holomorphy; continuity principle; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Abstract : The notion of polynomial hulls of compact subsets of complex Euclidean space plays a crucial role for approximation of holomorphic functions by polynomials - a topic which has many applications. Despite an abstract characterization of polynomial hulls in terms of currents, given by Duval and Sibony, it is often very difficult even for special classes of sets to decide whether the polynomial hull is trivial (i.
