This is a systematic mathematical study of differential (and more general self-adjoint) operators.

This volume provides a comprehensive review of multiple-scale dynamical systems. Mathematical models of such multiple-scale systems are considered singular pert

This book results from various lectures given in recent years. Early drafts were used for several single semester courses on singular perturbation meth ods give
