Main Page See live article Alphabetical index Calculus of variations Calculus of variations is a field of mathematics which deals with functions of functions, as opposed to ordinary calculus which deals with functions of numbers. 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. Some classical problems on curves were posed in this form: one example is the brachistochrone , the path along which a particle would descend under gravity in the shortest time from a given point A to a point B not directly beneath it. Amongst the curves from A to B one has to minimise the expression representing the time of descent. The key theorem of calculus of variations is the Euler-Lagrange equation . This corresponds to the stationary condition on a functional. As in the case of finding the maxima and minima of a function, the analysis of small changes round a supposed solution gives a condition, to first order. It cannot tell one directly whether a maximum or minimum has been found. Variational methods are important in theoretical physics : in Lagrangian mechanics and in application of the principle of stationary action to quantum mechanics . They were also much used in the past in pure mathematics, for example the use of the

32. CALCULUS OF VARIATIONS The calculus of variations arose from the attempts that were made by p ~j,, mathematicians in the 17th centur. calculus of variations. http://70.1911encyclopedia.org/V/VA/VARIATIONS_CALCULUS_OF.htm

CALCULUS OF VARIATIONS VARIATIONS, CALCULUS OF The first general theory of such problems was sketched by Leonhard Euler in 1736, and was more fully developed by him in his Euler treatise Methodus inveniendi - . - published in 1744. and he concluded that the differential equation obtained by equating to zero the expression in the square brackets must be satisfied. This equation is in general of the 2nth order, and the 2fl arbitrary constants which are contained in the complete ,primitive must be adjusted to satisfy the conditions that y, y, y, . . . y(~i) have given values at the limits of integration. If the function y is required also to satisfy the condition that another integral of the same form as the above, but containing a function 4, instead of F, may have a prescribed value, Euler achieved his purpose by replacing F in the differential equation by ~ and adjusting the constantA so that the condition may be satisfied. This artifice is known as the isoperimetric rule or rule of the undetermined multiplier. Euler illustrated his methods by a large number of examples. By means of these equations foZ can be transformed by the process of integration by parts into such a form that differentials of variations occur at the limits of integration only, and the The transformed integral contains no differentials of varia- b 11 tions. The terms at the limits and the integrand of 5~m ~

Modern Problems in Calculus of Variations Instructor Andrej Cherkaev Office: JWB 225 Telephone: 581-6822 E-mail: cherk@math.utah.edu Summary Every problem of the calculus of variations has a solution, provided that the word `solution' is suitably understood. David Hilbert Course description The course introduces classical methods of Calculus of Variations, Legendre transform, conservation laws and symmetries. The attention is paid to variational problems with unstable (highly oscillatory) solutions, especially in multidimensional problems. These problems arrive in large number of applications, including structural optimization, phase transitions, composites, inverse problems, etc., where an optimal layout are characterized by short scale inhomogenuities: patterns of unknown shapes. We discuss methods of effective description of such solutions. They are called relaxation methods and are based on theory of quasiconvexity. Topics to be covered: Basic techniques of Calculus of Variations. Euler equations, Legendre and Weierstrass tests, direct methods. Noether theory: symmetries and invariants.

Next: Parameter variations Up: No Title Previous: Hurwitz's proof of the Calculus of Variations formalism: necessary conditions The simplest and most common problems in the Calculus of Variations are of the type where we seek to minimize (or maximize) a functional where f f x z p ) is a given (say C ) function of its arguments and the function u x ) belongs to a certain admissible class, for example C functions or more generally perhaps piecewise C (or even Lipschitz) functions satisfying given boundary conditions u a A u b B where A,B are prescribed. Examples 3.1 The Brachistochrone problem, formulated by Johann Bernoulli in 1696 as a challenge problem to his colleagues , seeks among all curves joining two given points Pand Q, the path with the property that a frictionless particle acted on by gravity would have the minimum transit time. Earlier, Galileo had guessed that the circle might be the extremum and would likely be better than the straight line path. If we take the higher point as the origin of our coordinate system (in a vertical plane passing through PQ) with the y axis pointing down and the x axis to the right)and the second point as ( x y ) then where s is arc length ranging from to L and is the speed along the curve. From Newton's laws or conservation of energy, it is not difficult to show that
