6 CHAPTER 1. INTRODUCTION 1.1 Elements of function spaces As will become apparent in subsequent chapters, the accuracy of nite element ap-proximations to partial di erential equations very much depends on the smoothness of the analytical solution to the equation under consideration, and this in turn hinges on the smoothness of the data.
