  2. 6. Studies in the Conceptual Development of Mathematical Analysis

    Author : Kajsa Bråting; Anders Öberg; Hans Niels Jahnke; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; History of mathematics; conceptual development; mathematical analysis; Other mathematics; Övrig matematik; Mathematics; Matematik;

    Abstract : This dissertation deals with the development of mathematical concepts from a historical and didactical perspective. In particular, the development of concepts in mathematical analysis during the 19th century is considered. The thesis consists of a summary and three papers. In the first paper we investigate the Swedish mathematician E. READ MORE

  4. 7. Chordal and Complete Structures in Combinatorics and Commutative Algebra

    Author : Eric Emtander; Jörgen Backelin; Ralf Fröberg; Bernd Sturmfels; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Betti numbers; chordal hypergraphs; complete hypergraphs; hypercycle; line hypergraph; numerical monoids; positive affine monoids; Other mathematics; Övrig matematik; matematik; Mathematics;

    Abstract : This thesis is divided into two parts. The first part is concerned with the commutative algebra of certain combinatorial structures arising from uniform hypergraphs. The main focus lies on two particular classes of hypergraphs called chordal hypergraphs and complete hypergraphs, respectively. READ MORE

  5. 8. On various aspects of extended objects

    Author : Mariusz Hynek; Jens Hoppe; Volker Bach; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics;

    Abstract : This thesis concerns classical and quantum aspects of minimal manifolds embedded in flat Minkowski space. In particular, we study the Lie algebra of diffeomorphisms on 2 dimensional compact manifolds as well as discuss singularity formation for relativistic minimal surfaces in co-dimension one.

  6. 9. Limit shapes of standard Young tableaux and sorting networks via the Edelman-Greene correspondence

    Author : Samu Potka; Svante Linusson; Niklas Eriksen; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics;

    Abstract : This thesis consists of the following two articles.New properties of the Edelman–Greene bijection. Edelman and Greene constructed a correspondence between reduced words of the reverse permutation and standard Young tableaux. READ MORE

  7. 10. Digital lines, Sturmian words, and continued fractions

    Author : Hanna Uscka-Wehlou; Christer Oscar Kiselman; Maciej Klimek; Gunilla Borgefors; Mikael Passare; Damien Jamet; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; digital geometry; digital line; hierarchy of runs; combinatorics on words; Sturmian word; upper mechanical word; characteristic word; irrational slope; continued fraction; Gauss map; fixed point; Discrete mathematics; Diskret matematik; matematik; Mathematics;

    Abstract : In this thesis we present and solve selected problems arising from digital geometry and combinatorics on words. We consider digital straight lines and, equivalently, upper mechanical words with positive irrational slopes a... READ MORE
