Calculus of variations From Wikipedia, the free encyclopedia Jump to: navigation search Calculus of variations is a field of mathematics that deals with functionals , as opposed to ordinary calculus which deals with functions . Such functionals can for example be formed as integrals involving an unknown function and its derivatives. The interest is in extremal functions: those making the functional attain a maximum or minimum value. Perhaps the simplest example of such a problem is to find the curve of shortest length connecting two points. If there are no constraints, the solution is obviously a straight line between the points. However, if the curve is constrained to lie on a surface in space, then the solution is less obvious, and possibly many solutions may exist. Such solutions are known as geodesics . A related problem is posed by Fermat's principle : light follows the path of shortest optical length connecting two points, where the optical length depends upon the material of the medium. One corresponding concept in mechanics is the principle of least action . The theory of optimal control concerns a specific kind of problem in the calculus of variations.

ABOUT: Introduction History Related areas Subfields POINTERS: Texts Software Web links Selected topics here 49: Calculus of variations and optimal control; optimization Introduction Calculus of variations and optimization seek functions or geometric objects which are optimize some objective function. Certainly this includes a discussion of techniques to find the optima, such as successive approximations or linear programming. In addition, there is quite a lot of work establishing the existence of optima and characterizing them. In many cases, optimal functions or curves can be expressed as solutions to differential equations. Common applications include seeking curves and surfaces which are minimal in some sense. However, the spaces on which the analysis are done may represent configurations of some physical system, say, so that this field also applies to optimization problems in economics or control theory for example.

Join Our Mailing List INTRODUCTION TO THE CALCULUS OF VARIATIONS by Bernard Dacorogna (Ecole Polytechnique Fédérale, Switzerland) Table of Contents Preface Chapter 0: Introduction The calculus of variations is one of the oldest subjects in mathematics, yet is very much alive and is still evolving. Besides its mathematical importance and its links to other branches of mathematics, such as geometry or differential equations, it is widely used in physics, engineering, economics and biology. This book serves both as a guide to the expansive existing literature and as an aid to the non-specialist — mathematicians, physicists, engineers, students or researchers — in discovering the subjects most important problems, results and techniques. Despite the aim of addressing non-specialists, mathematical rigor has not been sacrificed; most of the theorems are either fully proved or proved under more stringent conditions. The book, containing more than seventy exercises with detailed solutions, is well designed for a course both at the undergraduate and graduate levels.

Chapter 8 CALCULUS OF VARIATIONS Introduction Euler Equation Functions, Functionals and Neighborhoods More Complex Problems ... Problems Constrained Variational Problems top Generally, there are two procedures used for solving variational problems that have constraints. These are the methods of direct substitution and Lagrange multipliers. In the method of direct substitution, the constraint equation is substituted into the integrand; and the problem is converted into an unconstrained problem as was done in Chapter II. In the method of Lagrange multipliers, the Lagrangian function is formed; and the unconstrained problem is solved using the appropriate forms of the Euler or Euler-Poisson equation. However, in some cases the Lagrange multiplier is a function of the independent variables and is not a constant. This is an added complication that was not encountered in Chapter II. Algebraic Constraints top To illustrate the method of Lagrange multipliers, the simplest case with one algebraic equation will be used. The extension to more complicated cases are the same as that for analytical methods:

Denied by her brother, the killer of her husband, a share of the golden throne of the ancient Phoenician city of Tyre, Dido convinces her brother's servants and some senators to flee with her across the sea in boats laden with her husband's gold. After a brief stop in Cyprus to pick up a priest and to "acquire" some wives for the men, the boats continue, rather lower in the water, to the Northern coast of Africa. Landing in modern-day Tunisia, Dido requests a small piece of land to rest on, only for a little while, and only as big as could be surrounded by the leather from a single oxhide. "Sure," the locals probably thought, "We can spare such a trifling bit of land."
