1. 1. On numbers badly approximable by q-adic rationals

   Författare :Johan Nilsson; Matematik LTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Number theory; Symbolic dynamics; Combinatorics on words; Badly approximable numbers; Diophantine approximation; Mathematics; Matematik; Dynamical systems;

   Sammanfattning : The thesis takes as starting point diophantine approximation with focus on the area of badly approximable numbers. For the special kind of rationals, the q-adic rationals, we consider two types of approimations models, a one-sided and a two-sided model, and the sets of badly approximable numbers they give rise to.

3. 2. Children’s early mathematics learning and development : Number game interventions and number line estimations

   Författare :Jessica Elofsson; Ulf Träff; Joakim Samuelsson; Stefan Gustafson; Camilla Björklund; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematics learning and development; number knowledge and skills; intervention; number games; number line estimation; representations of number; lärande och utveckling i matematik; numeriska kunskaper och färdigheter; intervention; numeriska spel; skattningar av tal på tallinjer; representationer av tal.;

   Sammanfattning : Children’s early mathematics learning and development have become a topic of increasing interest over the past decade since early mathematical knowledge and skills have been shown to be a strong predictor of later mathematics performance. Understanding how children develop mathematical knowledge and skills and how they can be supported in their early learning could thus prove to be a vital component in promoting learning of more formal mathematics.

4. 3. Dynamics of Smooth Hyperbolic Systems with Singularities

   Författare :Tomas Persson; Dynamiska system; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics; Dimension Theory; Hyperbolic Dynamics; Subshift; SRB-measure;

   Sammanfattning : This thesis is about dynamics of piecewise hyperbolic maps on bounded sets in the plane and on the interval. It is based on the following papers: T. Persson, A piecewise hyperbolic map with absolutely continuous invariant measure, Dynamical Systems: An International Journal, 21:3 (2006), 363--378 T. LÄS MER

5. 4. The meaning(s) of inclusion in mathematics in student talk : Inclusion as a topic when students talk about learning and teaching in mathematics

   Författare :Helena Roos; Despina Potari; Hanna Palmér; Nùria Planas; Linnéuniversitetet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; inclusion in mathematics; discourse analysis; students meaning s ; Matematikens didaktik; Mathematics education; Mathematical Education;

   Sammanfattning : This thesis contributes to research and practice within the field of special education in mathematics with more knowledge about, and an understanding of, students´ meaning(s) of inclusion in mathematics education. Three research questions guide the study: What meaning(s) is/are ascribed, and how is inclusion used, in mathematics education research? What meaning(s) do the students ascribe to inclusion in mathematics learning and teaching? And what frames students´ meaning(s) of inclusion in mathematics learning and teaching?The first part of this study began with a systematic literature review on the notion of inclusion in mathematics education research, and the search resulted in 1,296 research studies.
