This book is intended to be used as a rather informal, and surely not complete, textbook on the subjects indicated in the title. It collects my Lecture Notes he

Incomplete second order linear differential equations in Banach spaces as well as first order equations have become a classical part of functional analysis. Thi

This book consists of two main parts. The first part, "Hyperbolic and Parabolic Equations", written by F. John, contains a well-chosen assortment of material in
