Homogenization in Time of Singularly Perturbed Mechanical Systems

This book is about the explicit elimination of fast oscillatory scales in dynamical systems, which is important for efficient computer-simulations and our understanding of model hierarchies. The author presents his new direct method, homogenization in tim

in memoriam Alfred Neumann (1902-1982)

Preface Although the title might suggest it differently, this monograph is about a certain method for establishing singular limits rather than about a clearcut class of singularly perturbed problems. Using this particular method I will address in a unified way such diverse topics as the micro-scale justification of the Lagrange-d'Alembert principle and the limit behavior of strong constraining potentials in classical mechanics on the one hand, and the adiabatic theorem of quantum mechanics on the other hand. I am confident that all these topics are cases of a larger class of singularly perturbed mechanical systems that show up rapid micro-scale fluctuations, allowing for the application of the method to be presented. Reflecting this, I have tried to apply the method to each case as directly as possible and refrained from studying an abstract super-class of problems which would leave the cases as mere examples. I believe th
