1. 11. On avoiding and completing colorings

   Författare :Lan Anh Pham; Klas Markström; Carl Johan Casselgren; Victor Falgas-Ravry; Roland Häggkvist; Kimmo Eriksson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Graph coloring; precoloring; list assignment;

   Sammanfattning : All of my papers are related to the problem of avoiding and completing an edge precoloring of a graph. In more detail, given a graph G and a partial proper edge precoloring φ of G and a list assignment L for every non-colored edge of G, can we extend φ to a proper edge coloring of G which avoids L? In Paper I, G is the d-dimensional hypercube graph Qd, a partial proper edge precoloring φ and a list assignment L must satisfy certain sparsity conditions.

3. 12. Approaching Mathematical Discourse : Two analytical frameworks and their relation to problem solving interactions

   Författare :Andreas Ryve; Kimmo Eriksson; Inger Wistedt; Anna Sfard; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Didactics of Mathematics; Mathematics Education; Analytical approaches; Communication; Concept maps; Contextualization; Discourse; Engineering students; Higher Education; Intentional analysis; Methodological framworks; Problem solving; Prospective teachers; Student teachers; Teacher education; Theoretical frameworks; MATHEMATICS; MATEMATIK; Matematik tillämpad matematik;

   Sammanfattning : The driving force of conducting the two studies presented in this thesis is to examine ways that conceptual understanding and problem solving could be part of mathematics teaching, and through that, part of students' mathematical knowledge. The specific aims of the thesis are: 1) to characterize the classroom discourse of two, apparently similar, problem solving courses in teacher education and 2) to discuss the possibilities of developing two analytical approaches - the communicational approach to cognition and the dialogical approach - used for studying mathematical discourse.

5. 14. Semi-Markov Models for Insurance and Option Rewards

   Författare :Fredrik Stenberg; Dmitrii Silvestrov; Kimmo Eriksson; Nikolaos Limnios; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; semi-Markov process; discrete time; insurance; actuarial; higher order reward; disability; variance; skewness; kurtosis; reward process; stochastic volatility; controlling semi-Markov process; Monte Carlo algorithm; convergence; optimal stopping; skeleton approximation; regime switching; semi-Markov modulated; European option; American option; Lévy process.; MATHEMATICS; MATEMATIK; Matematik tillämpad matematik;

   Sammanfattning : This thesis presents studies of semi-Markov models for insurance and option rewards. The thesis consists of the introduction and six papers. The introduction presents the results of the thesis in an informal way.In paper A, a general semi-Markov reward model is presented. LÄS MER

7. 15. What Will We Learn? : A Mathematical Treatise of Cultural Evolution

   Författare :Pontus Strimling; Kimmo Eriksson; Robert Boyd; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cultural Evolution; Mathematical modeling; Applied mathematics; Tillämpad matematik; Matematik tillämpad matematik;

   Sammanfattning : In this thesis we apply mathematics and formal modeling to study culture from an evolutionary standpoint. Cultural evolution theory is based on the belief that we can increase our understanding of human behavior by studying how culture is created and spread. LÄS MER
