1. Homogenization applied to some problems in mechanics
Sammanfattning : .... LÄS MER
2. Some modes of convergence and their application to homogenization and optimal composites design
Sammanfattning : In this thesis, we develop, extend, apply, and discuss a number of methods for the study of limits of sequences of functions and operators. The connection between the notion of two-scale convergence and more general concepts of convergence is investigated and some alternative classes of admissible test functions are characterized. LÄS MER
3. 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
4. G-Convergence and Homogenization of some Sequences of Monotone Differential Operators
Sammanfattning : This thesis mainly deals with questions concerning the convergence of some sequences of elliptic and parabolic linear and non-linear operators by means of G-convergence and homogenization. In particular, we study operators with oscillations in several spatial and temporal scales. LÄS MER
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
