  1. 1. On axioms and images in the history of Mathematics

    Detta är en avhandling från Uppsala : Department of Mathematics, Uppsala University

    Författare :Johanna Pejlare; Uppsala universitet.; Högskolan i Borås.; Göteborgs universitet.; Gothenburg University.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; MATHEMATICS; MATEMATIK; Mathematics; History of mathematics; axiomatization; intuition; visualization; images; Euclidean geometry; history of mathematics; euclidean geometry; matematikhistoria;

    Sammanfattning : This dissertation deals with aspects of axiomatization, intuition and visualization in the history of mathematics. Particular focus is put on the end of the 19th century, before David Hilbert's (1862–1943) work on the axiomatization of Euclidean geometry. The thesis consists of three papers. LÄS MER

  2. 2. Vector-valued Eisenstein series of congruence types and their products

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Jiacheng Xia; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hecke operator; Fourier expansion of modular forms; congruence type; products of Eisenstein series; vector-valued modular forms;

    Sammanfattning : Historically, Kohnen and Zagier connected modular forms with period polynomials, and as a consequence of this association concluded that the products of at most two Eisenstein series span all spaces of classical modular forms of level 1. Later Borisov and Gunnells among other authors extended the result to higher levels. LÄS MER

  3. 3. Selected Topics in Partial Differential Equations

    Detta är en avhandling från Uppsala : Department of Mathematics

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK; MATHEMATICS Applied mathematics; MATEMATIK Tillämpad matematik;

    Sammanfattning : 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. LÄS MER

  4. 4. Samspel mellan intuitiva idéer och formella bevis en fallstudie av universitetsstudenters arbete med en analysuppgift

    Detta är en avhandling från Chalmers tekniska högskola och Göteborgs Universitet

    Författare :Kerstin Pettersson; Högskolan i Skövde.; Göteborgs universitet.; Gothenburg University.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK; MATHEMATICS; MATEMATIK; MATHEMATICS; MATEMATIK;

    Sammanfattning : The aim of this study is to illuminate the interplay between intuitive ideas and formal justification. In a perspective where we focus on the students’ competences we describe the interaction between intuitive ideas and formal structures, as they appear especially in relation to concept definitions and formal proofs.

  5. 5. Generalized Vandermonde matrices and determinants in electromagnetic compatibility

    Detta är en avhandling från Västerås : Mälardalen University

    Författare :Karl Lundengård; Mälardalens högskola.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Sammanfattning : Matrices whose rows (or columns) consists of monomials of sequential powers are called Vandermonde matrices and can be used to describe several useful concepts and have properties that can be helpful for solving many kinds of problems. In this thesis we will discuss this matrix and some of its properties as well as a generalization of it and how it can be applied to curve fitting discharge current for the purpose of ensuring electromagnetic compatibility.
