    Abstract : Popular Abstract in Swedish Även om vi kanske inte tänker på det så ofta så är vår förmåga att bedöma likhet av stor vikt, inte minst då det gäller begreppsbildning och generalisering. Denna avhandling handlar om likhet, speciellt geometriska modeller av likhet. READ MORE

  3. 3. Multivariable Orthogonal Polynomials as Coupling Coefficients for Lie and Quantum Algebra Representations

    University dissertation from Centre for Mathematical Sciences, Lund University

    Author : Hjalmar Rosengren; Lunds universitet.; Lund University.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; higher order Hankel form; Wigner symbol; quadratic algebra; Clebsch-Gordan coefficient; quantum group; Lie group; highest weight representation; multivariable orthogonal and biorthogonal polynomials; multivariable hypergeometric and basic hypergeometric functions; algebraisk topologi; Geometry; Geometri; algebraic topology;

    Abstract : The main topic of the thesis is the connection between representation theory and special functions. We study matrix elements, coupling coefficient, and recoupling coefficients for the simplest Lie and quantum groups. READ MORE

  4. 4. Complexes and Diffrerential Graded Modules

    University dissertation from Centre for Mathematical Sciences, Lund University

    Author : Dmitri Apassov; Lunds universitet.; Lund University.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; algebraic geometry; field theory; Number Theory; fiber of a local homomorphism; DG dualizing module; homological dimensions; differential graded rings; almost finite module; Cohen-Macaulay rings; local homomorphism; Gorenstein rings; annihilator; complex of modules; algebra; group theory; Talteori; fältteori; algebraisk geometri; gruppteori;

    Abstract : Popular Abstract in Swedish I avhandlingen studeras olika resolvent uppskattningar i harmonisk analys. I det första arbetet visas en Wiener taubersats med hjälp av resolventtransformen. I det andra arbetet studeras kvantitativa förfiningar av Wieners lemma i kommutativa kvasi-Banachalgebror och även i Banachalgebror. READ MORE
