1. 1. Varför undervisning i matematik? : argument för matematik i grundskolan - i läroplaner, läroplansdebatt och hos blivande lärare

   Författare :Maria Bjerneby Häll; Bertil Askling; Hans Wallin; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Arguments for Mathematics; Curriculum in Mathematics; School Mathematics; Student Teachers in Mathematics; Matematikundervisning; grundskolan; Mathematics; Educational Science;

   Sammanfattning : The aim of this study is to investigate, describe and analyse the justification and the goals of mathematics education in compulsory school in Sweden. The focus here is on student teachers and their conceptions of why mathematics should be taught in school. LÄS MER

3. 2. Automorphic string amplitudes

   Författare :Henrik Gustafsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Eisenstein series; string theory; automorphic forms; U-duality; non-perturbative effects; Whittaker vectors; instantons;

   Sammanfattning : This thesis explores the non-perturbative properties of higher derivative interactions appearing in the low-energy expansion of four-graviton scattering amplitudes in toroidal compactifications of type IIB string theory. We summarise the arguments for finding such higher derivative corrections in terms of automorphic forms using U-duality, supersymmetry and string perturbation theory. LÄS MER

4. 3. "Vad skulle x kunna vara?" : andragradsekvation och andragradsfunktion som objekt för lärande

   Författare :Constanta Olteanu; Shirley Booth; Torgny Ottosson; Ingemar Holgersson; Umeå universitet; []
   Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURAL SCIENCES; NATURVETENSKAP; parameters; unknown quantity; argument; second degree equations; quadratic functions; teaching; mathematics education; experience; theory of variation; dimensions of variation; Education; Pedagogik; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; MATHEMATICS; MATEMATIK;

   Sammanfattning : Algebraic equations and functions play an important role in various mathematical topics, including algebra, trigonometry, linear programming and calculus. Accordingly, various documents, such as the most recent Swedish curriculum (Lpf 94) for upper secondary school and the course syllabi in mathematics, specify what the students should learn in Mathematics Course B.

7. 5. Homogenization of reaction-diffusion problems with nonlinear drift in thin structures

   Författare :Vishnu Raveendran; Adrian Muntean; Emilio N.M. Cirillo; Claudia Timofte; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Thin layer; homogenization; dimension reduction; reaction-diffusion-convection problem; two-scale convergence; effective transmission condition; fast drift; weak solvability of quasi-linear parabolic systems in unbounded domains.; Matematik; Mathematics;

   Sammanfattning : We study the question of periodic homogenization of a variably scaled reaction-diffusion equation with non-linear drift of polynomial type. The non-linear drift was derived as hydrodynamic limit of a totally asymmetric simple exclusion process (TASEP) for a population of interacting particles crossing a domain with obstacle. LÄS MER
