2. 1. On linear graph invariants related to Ramsey and edge numbers : or how I learned to stop worrying and love the alien invasion

   Author : Oliver Krüger; Jörgen Backelin; Alexander Engström; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ramsey number; edge number; minimal Ramsey graph; independence number; clique number; Turán s theorem; crochet pattern; H13-pattern; linear graph invariant; triangle-free graph; Mathematics; matematik;

   Abstract : In this thesis we study the Ramsey numbers, R(l,k), the edge numbers, e(l,k;n) and graphs that are related to these. The edge number e(l,k;n) may be defined as the least natural number m for which all graphs on n vertices and less than m edges either contains a complete subgraph of size l or an independent set of size k.

   Abstract : 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.

6. 4. Gender and its interaction with number and evaluative morphology : An intra- and intergenealogical typological survey of Africa

   Author : Francesca Di Garbo; Maria Koptjevskaja Tamm; Ljuba Veselinova; Vladimir Plungian; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; Gender; number; evaluative morphology; interaction; grammatical complexity; Africa; Linguistics; lingvistik;

   Abstract : This dissertation investigates interactions between gender and number and gender and evaluative morphology in a sample of 100 African languages, and provides a method for assessing the role that these interactions play in the grammatical complexity of gender systems. The dissertation is organised around three research foci. READ MORE

7. 5. Making Sense of Negative Numbers

   Author : Cecilia Kilhamn; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematics education; metaphor; signed number; negative number; number sense; case study; longitudinal; social constructivism;

   Abstract : Numbers are abstract objects that we conceptualize and make sense of through metaphors. When negative numbers appear in school mathematics, some properties of number sense related to natural numbers become contradictory. The metaphors seem to break down, making a transition from intuitive to formal mathematics necessary. READ MORE
