1. Partial Balayage and Related Concepts in Potential Theory
Sammanfattning : This thesis consists of three papers, all treating various aspects of the operation partial balayage from potential theory.The first paper concerns the equilibrium measure in the setting of two dimensional weighted potential theory, an important measure arising in various mathematical areas, e.g. LÄS MER
2. Traces of Mathematical Facts and Students’ Understanding of the Concept `Quadrilateral´ : An enquiry into young students’ communication
Sammanfattning : Mathematics could be described as a special kind of language, a discourse in which participants communicate abstract concepts. Communication and language are known to be important factors in teaching and learning but little is known about neither communication between students in relation to geometrical concepts, nor what traces of mathematical facts and understanding is incorporated into their communication. LÄS MER
3. Group theoretical methods for solving multidimensional nonlinear partial differential equations
Sammanfattning : New methods for constructing both exact and approximate solutions of multidimensional nonlinear partial differential equations are developed. The basis of the methods is taken from the classical Lie transformation group theory. LÄS MER
4. Pedagogic practice between tradition and renewal : A study of the new mathematics curriculum in Mozambique
Sammanfattning : The new school mathematics curriculum in Mozambique, introduced in 2008, is partly competency-based and it advocates a more student-centred pedagogy. The most salient innovative features are the incorporation of mathematical competencies related to the development of students’ reasoning skills, including argumentation, justification and analytical thinking, and the use of heuristic or inductive methods that promote meaningful students’ participation.

5. Homogenization of Partial Differential Equations using Multiscale Convergence Methods
Sammanfattning : The focus of this thesis is the theory of periodic homogenization of partial differential equations and some applicable concepts of convergence. More precisely, we study parabolic problems exhibiting both spatial and temporal microscopic oscillations and a vanishing volumetric heat capacity type of coefficient. LÄS MER
