  1. 1. Matematikämnet och stadiebytet mellan grundskolan och gymnasieskolan : En enkät- och klassrumsstudie

    Författare :Niclas Larson; Christer Bergsten; Lisa Björklund Boistrup; Kirsti Hemmi; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematics education; career choice; transition; framing; Matematik; undervisning; gymnasieval; stadiebyte; inramning;

    Sammanfattning : Studiens övergripande syfte var att undersöka matematikutbildningen och matematikämnets roll i samband med stadiebytet från grund- till gymnasieskolan. Studien styrdes av två forskningsfrågor gällande den bild eleverna ger av matematikämnets betydelse för deras val av gymnasieprogram samt vad som karaktäriserar matematikutbildningen i årskurs 9 och gymnasiets årskurs 1.

  3. 2. Tame representations in Topological Data Analysis: decompositions, invariants and metrics

    Författare :Francesca Tombari; Wojciech Chachólski; Patrizio Frosini; Peter Bubenik; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; topological data analysis; tameness; decompositions; invariants; metrics; Matematik; Mathematics;

    Sammanfattning : This thesis is a compilation of results that can be framed within the field of applied topology. The starting point of our study is objects presenting a possibly complex intrinsic geometry. The main goal is then to simplify, without trivializing, the geometric information characterising these objects by choosing an appropriate representation.

  4. 3. Quiescent regimes in cosmology

    Författare :Hans Oude Groeniger; Hans Ringström; Mattias Dahl; Todd Oliynyk; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quiescence; Bianchi spacetimes; big bang formation; G2 cosmology; Wainwright-Hsu variables; Klein-Gordon equation; Matematik; Mathematics;

    Sammanfattning : This thesis is about cosmological solutions to Einstein’s equations of general relativity, in particular spacetimes whose mean curvature diverges. Moreover, we consider anisotropic spacetimes with big bang singularities. In this setting the singularity is expected to generically be oscillatory if no matter is present. LÄS MER

  5. 4. Enumerative combinatorics related to partition shapes

    Författare :Jonas Sjöstrand; Anders Björner; Christian Krattenthaler; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; partition shape; sign-imbalance; Robinson-Schensted correspondence; chess tableau; restricted word; cylindrical lattice walk; Poincaré polynomial; Bruhat interval; rook polynomial; pattern avoidance; partitionsform; teckenobalans; Robinson-Schensted-korrespondens; schacktablå; begränsade ord; cylindriska latticestigar; poincarépolynom; bruhatintervall; tornpolynom; mönsterundvikande permutation; MATHEMATICS; MATEMATIK;

    Sammanfattning : This thesis deals with enumerative combinatorics applied to three different objects related to partition shapes, namely tableaux, restricted words, and Bruhat intervals. The main scientific contributions are the following. LÄS MER

  7. 5. Graphical representations of Ising and Potts models : Stochastic geometry of the quantum Ising model and the space-time Potts model

    Författare :Jakob Erik Björnberg; Anders Björner; Jeffrey Steif; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum Ising model; Ising model; Potts model; random-cluster model; random-current representation; random-parity representation; differential inequality; phase transition; Discrete mathematics; Diskret matematik;

    Sammanfattning : HTML clipboard Statistical physics seeks to explain macroscopic properties of matter in terms of microscopic interactions. Of particular interest is the phenomenon of phase transition: the sudden changes in macroscopic properties as external conditions are varied. LÄS MER
