These notes are just a basic introduction. We refer the reader to [28, Chapter 8] and [22] for a more thorough exposition of the theory behind the Calculus of Variations. 1.1 Examples Webeginwithsomeexamples. Example 1.1 (Shortest path). Let Aand B be two points in the plane. What is the shortest path between Aand B? The answer depends on how ...

The Calculus of Variations is concerned with solving Extremal Problems for a Func-tional. That is to say Maximum and Minimum problems for functions whose domain con-tains functions, Y(x) (or Y(x1;¢¢¢x2), or n-tuples of functions). The range of the functional will be the real numbers, R Examples: I.

Calculus of variations is a subject that deals with functionals. So in order to understand the method of calculus of variations, we rst need to know what functionals are. In a very short way, a functional is a function of a function. To make it more clear what a functional is, we compare it to functions. 2.1 Functions Consider the function y= f(x).

These lecture notes are intented as a straightforward introduction to the calculus of variations which can serve as a textbook for undergraduate and beginning graduate students. The main body of Chapter 2 consists of well known results concerning necessary or sufficient criteria for local minimizers, including Lagrange mul-

Preface These lecture notes, written for the MA4G6 Calculus of Variations course at the University of Warwick, intend to give a modern introduction to the Calculus of Variations. I have tried to cover different aspects of the field and to explain how they fit into the “big picture”.

This section is also the opening to control theory—the modern form of the calculus of variations. Its constraints are differential equations, and Pontryagin's.
