1. Skolans matematik : En kritisk analys av den svenska skolmatematikens förhistoria, uppkomst och utveckling
Sammanfattning : I argue that common beliefs regarding mathematics originate in the practices of elementary mathematics instruction rather than in science. While learning how to solve mathematical problems in school, we come to believe that mathematics has a set of properties in itself, for instance that it is useful in everyday life, even though this is not necessarily so.

Sammanfattning : We study admissible transformations and solve group classification problems for various classes of linear and nonlinear Schrödinger equations with an arbitrary number n of space variables.The aim of the thesis is twofold. LÄS MER
Sammanfattning : The theory of generalized operads, the foundational conceptual framework of this thesis, has become a universal language, relating various areas such as algebraic topology, derived categories of algebras, deformation theory, differential geometry and the mathematical theory of quantization.The thesis consists of a preliminary chapter followed by four main chapters.

Sammanfattning : This thesis concerns classical and quantum aspects of minimal manifolds embedded in flat Minkowski space. In particular, we study the Lie algebra of diffeomorphisms on 2 dimensional compact manifolds as well as discuss singularity formation for relativistic minimal surfaces in co-dimension one. LÄS MER
Sammanfattning : This thesis in applied mathematics is devoted to some theoretical, numerical and technical aspects of the homogenization theory, and has obviously been deeply influented by interactions between mathematicians with knowledge in homogenization theory, scientists in composite engineering and the industry. It contains a number of theoretical, numerical and technical aspects of the homogenization theory and its applications. LÄS MER
