1. 1. The Diamond Lemma for Power Series Algebras

   Författare :Lars Hellström; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; diamond lemma; power series algebra; Gröbner basis; embedding into skew fields; archimedean element in semigroup; q-deformed Heisenberg--Weyl algebra; polynomial degree; ring norm; Birkhoff orthogonality; filtered structure; Matematisk analys; Mathematical analysis; Analys; Mathematics; matematik;

   Sammanfattning : The main result in this thesis is the generalisation of Bergman's diamond lemma for ring theory to power series rings. This generalisation makes it possible to treat problems in which there arise infinite descending chains. LÄS MER

3. 2. Promoting mathematical dialogue : students’ and teachers’ listening, questioning and participation

   Författare :Marie Sjöblom; Clas Olander; Paola Valero; Despina Potari; Malmö universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Listening; mathematical dialogue; mathematics education; noticing; participation; professional development; questioning;

   Sammanfattning : In Swedish mathematics classrooms, students have different opportunities to participate in mathematical dialogue, and therefore also different opportunities to learn. This is a problem not only for students, but also for teachers, school developers, and researchers. LÄS MER

4. 3. Problem-solving can reveal mathematical abilities : How to detect students' abilities in mathematical activities

   Författare :Thomas Dahl; Inger Wistedt; Astrid Pettersson; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical Education; Matematikdidaktik;

   Sammanfattning : Dahl, Thomas (2012). Problemlösning kan avslöja matematiska förmågor. Att upptäcka matematiska förmågor i en matematisk aktivitet (Problem-solving can reveal mathematical abilities: How to detect students‟ abilities in mathematical activities).

5. 4. Some new Friedrichs-type inequalities in domains with microinhomogeneous structure

   Författare :Yulia Koroleva; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

   Sammanfattning : This Licentiate thesis is devoted to derive and discuss some new Friedrichs-type inequalities for functions, which belong to the Sobolev space $H^1$ in domains with microinhomogeneous structure and which vanish on a part of the boundary. The classical Friedrics inequality holds for functions from the space $\mathop{H^{\smash 1}}\limits^{\circ}$ with a constant depending only on the measure of the domain. LÄS MER

7. 5. Linear and Non-linear Deformations of Stochastic Processes

   Författare :Gustaf Strandell; Maciej Klimek; Richard Aron; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; Riesz bases and frames; Weakly stationary stochastic processes; Set-valued analysis; Matematisk analys; Mathematical analysis; Analys;

   Sammanfattning : This thesis consists of three papers on the following topics in functional analysis and probability theory: Riesz bases and frames, weakly stationary stochastic processes and analysis of set-valued stochastic processes. In the first paper we investigate Uniformly Bounded Linearly Stationary stochastic processes from the point of view of the theory of Riesz bases. LÄS MER
