1. Movement and experimentation in young children's learning : Deleuze and Guattari in early childhood education
Sammanfattning : This study departs from experiences made in a setting where preschool children, teachers, teacher students, teacher educators and researchers in the Stockholm area in Sweden have been collectively experimenting with subjectivity and learning since the beginning of the 1990’s. However, during later years, questions were raised in the context of cooperative work about the changes that have been achieved so far, possibly becoming new and somewhat rigid ‘mappings’ of young children and learning.

2. Further Investigations of Convergence Results for Homogenization Problems with Various Combinations of Scales
Sammanfattning : This thesis is based on six papers. We study the homogenization of selected parabolic problems with one or more microscopic scales in space and time, respectively. LÄS MER
3. 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
4. Homogenization Results for Parabolic and Hyperbolic-Parabolic Problems and Further Results on Homogenization in Perforated Domains
Sammanfattning : This thesis is based on four papers. The main focus is on homogenization of selected parabolic problems with time oscillations, and hyperbolic-parabolic problems without time oscillations. The approaches are prepared by means of certain methods, such as two-scale convergence, multiscale convergence and evolution multiscale convergence. LÄS MER
5. Selected Topics in Homogenization
Sammanfattning : The main focus of the present thesis is on the homogenization of some selected elliptic and parabolic problems. More precisely, we homogenize: non-periodic linear elliptic problems in two dimensions exhibiting a homothetic scaling property; two types of evolution-multiscale linear parabolic problems, one having two spatial and two temporal microscopic scales where the latter ones are given in terms of a two-parameter family, and one having two spatial and three temporal microscopic scales that are fixed power functions; and, finally, evolution-multiscale monotone parabolic problems with one spatial and an arbitrary number of temporal microscopic scales that are not restricted to be given in terms of power functions.
