  1. 1. Rekonstruktion av logaritmer med tallinjer som medierande redskap

    Författare :Roger Fermsjö; Torbjörn Tambour; Inger Eriksson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Logarithms; Napier; Davydov; learning activity; learning action; learning tasks; mediated tool; learning study;

    Sammanfattning : The aim of the research reported in this licentiate thesis was to create an environment that could support students’ learning about logarithms. To develop such a learning environment, Davydov’s ‘learning activity’ was used as a theoretical framework for the design. LÄS MER

  3. 2. Weighted Bergman kernels and biharmonic Green functions

    Författare :Stefan Jakobsson; Matematikcentrum; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; singularity resolution of Bergman kernels; Hadamard s variational formula; weighted Bergman kernel; weighted biharmonic Green function; Friedrichs operator; Plant biochemistry; Växtbiokemi;

    Sammanfattning : The main theme of this thesis is the connection between weighted biharmonic Green functions and weighted Bergman kernels. In the first paper, which is a joint work with H. Hedenmalm and S. Shimorin, we prove that weighted biharmonic Green functions are positive for weights which satisfy a mean-value condition and whose logarithms are subharmonic. LÄS MER

  4. 3. Soft and Hard Mesons in Chiral Perturbation Theory

    Författare :Ilaria Jemos; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis deals with Chiral Perturbation Theory (ChPT), an effective field theory for the strong force used to describe meson interactions. The work done can be split in two parts. The first one is on ChPT in its standard formulation. This theory has been very successful so far in describing low energetic processes. LÄS MER

  5. 4. Soft resummation and hard evolution : Renormalization group methods in effective theories and multi scalar models

    Författare :Joel Oredsson; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Higgs; Particle physics; two-Higgs-doublet model; Soft-Collinear-Effective Theory; Renormalization;

    Sammanfattning : This thesis is composed out of five papers that deal with various problems intheoretical particle physics. While paper I is a precision calculation in aneffective theory of the Standard Model, paper II to V all deal with beyond theStandard Model physics. Paper IV is a manual for the tools developed during ourwork on paper II to V.Paper I. LÄS MER

  7. 5. Proof-related reasoning in upper secondary mathematics textbooks : Characteristics, comparisons, and conceptualizations

    Författare :Andreas Bergwall; Andreas Ryve; Kimmo Eriksson; Kristina Juter; Mälardalens högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematics textbook; upper secondary school; proof-related reasoning; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Sammanfattning : Proofs and proving are difficult to learn and difficult to teach. A common problem is that many students use specific examples as evidence for general statements. Difficulties with proofs are also part of the transition problems that exist between secondary and tertiary schooling in mathematics. LÄS MER
