  1. 1. 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.

  2. 2. Skolans matematik En kritisk analys av den svenska skolmatematikens förhistoria, uppkomst och utveckling

    Detta är en avhandling från Uppsala

    Författare :Sverker Lundin; Göteborgs universitet.; Gothenburg University.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; matematik; skolmatematik; historia;

    Sammanfattning : I argue that common beliefs regarding mathematics originate in the practices of elementary mathematics instruction rather than in science. While learning how to solve mathematical problems in school, we come to believe that mathematics has a set of properties in itself, for instance that it is useful in everyday life, even though this is not necessarily so.

  3. 3. 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

  4. 4. Classification of Normal Discrete Kinetic Models

    Detta är en avhandling från Karlstad : Karlstad University

    Författare :Mirela Christina Vinerean; Mirela Vinerean-Bernhoff; Karlstads universitet.; Karlstads universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK; Matematik; Mathematics; Kinetic theory; discrete kinetic velocity models; conservation laws;

    Sammanfattning : “In many interesting papers on discrete velocity models (DVMs), authors postulate from the beginning that the finite velocity space with "good" properties is given and only after this step they study the Discrete Boltzmann Equation. Contrary to this approach, our aim is not to study the equation, but to discuss all possible choices of finite phase spaces (sets) satisfying this type of "good" restrictions. LÄS MER

  5. 5. Admissible transformations and the group classification of Schrödinger equations

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Celestin Kurujyibwami; Linköpings universitet.; Linköpings universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : We study admissible transformations and solve group classification problems for various classes of linear and nonlinear Schrödinger equations with an arbitrary number n of space variables.The aim of the thesis is twofold. LÄS MER
