    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

  2. 2. Matematikproblem i skolan för att skapa tillfällen till lärande

    Detta är en avhandling från Umeå : Matematik och matematisk statistik

    Författare :Eva Taflin; Högskolan Dalarna.; Umeå universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; problem-solving; rich problem; teacher; instruction; learning; mathematical ideas; occasions; MATHEMATICS; MATEMATIK;

    Sammanfattning : The general purpose of this dissertation is to define and explore what mathematical problem solving entails. Seven criteria for rich problems will also be formulated. Rich problems are defined as problems which are especially constructed for mathematics education in a school context. LÄS MER

  3. 3. Generalized Vandermonde matrices and determinants in electromagnetic compatibility

    Detta är en avhandling från Västerås : Mälardalen University

    Författare :Karl Lundengård; Mälardalens högskola.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Sammanfattning : Matrices whose rows (or columns) consists of monomials of sequential powers are called Vandermonde matrices and can be used to describe several useful concepts and have properties that can be helpful for solving many kinds of problems. In this thesis we will discuss this matrix and some of its properties as well as a generalization of it and how it can be applied to curve fitting discharge current for the purpose of ensuring electromagnetic compatibility.

  4. 4. Weaknesses of Authentication in Quantum Cryptography and Strongly Universal Hash Functions

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Aysajan Abidin; Linköpings universitet.; Linköpings universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : Authentication is an indispensable part of Quantum Cryptography, which is an unconditionally secure key distribution technique based on the laws of nature. Without proper authentication, Quantum Cryptography is vulnerable to “man-in-the-middle” attacks. LÄS MER

  5. 5. Conformal Einstein spaces and Bach tensor generalization in n dimensions

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Jonas Bergman Ärlebäck; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : In this thesis we investigate necessary and su±cient conditions for an n-dimensional space, n ≥ 4, to be locally conformal to an Einstein space. After reviewing the classical results derived in tensors we consider the four-dimensional spinor result of Kozameh, Newman and Tod. LÄS MER
