We consider the aerodynamic Newton problem, problems of the minimum rotation-surface and of brachistochrone. The last problem is examined also in non-classical formulation. The demonstration software developed with the participation of students is applied to these problems. Keywords: Variational analysis, education, computer software, numerical methods, multiprocessor systems 1. AERODYNAMIC NEWTON'S PROBLEM (ANP) The problem consists of searching the generating line y(x) of a rotation-body with the minimum resistance in a flow of rarefied ideal gas ( Newton, 1916

TODO List calculus of variations (Topic) Imagine a bead of mass on a wire whose endpoints are at and , with lower than the starting position. If gravity acts on the bead with force , what path (arrangement of the wire) minimizes the bead's travel time from to , assuming no friction? This is the famed ``brachistochrone problem,'' and its solution was one of the first accomplishments of the calculus of variations. Many minimum problems can be solved using the techniques introduced here. In its general form, the calculus of variations concerns quantities for which we wish to find a minimum or a maximum. To make this concrete, let's consider a much simpler problem than the brachistochrone: what's the shortest distance between two points and ? Let the variable represent distance along the path, so that

24. Calculus Of Variations calculus of variations. Our research projects address both fundamental problemsin the calculus of variations and applications, eg in nonlinear elasticity. http://www.mis.mpg.de/sm/cvar/

MPI-MIS HOME Calculus of Variations Many problems in physics, biology, engineering are governed by a maximization or minimization principle (for example for energy, entropy, fitness, ...). The corresponding optimality condition (called Euler-Lagrange equation) is usually a nonlinear partial differential equation and one can apply pde methods to study the minimizers. It has become clear, however, that often much more powerful methods are available if one exploits the minimization principle directly. The corresponding branch of mathematics is called the calculus of variations (because originally the Euler-Lagrange equation was derived by studying small variations of supposed minimizer). One example for the power of minimization principle arises when one studies a family of minimization problems (e.g. posed on a sequence of increasingly thinner three-dimensional structures). There is a general theory due to DeGiorgi, called Gamma-convergence, which shows that there exists a limiting minimization problem. No similarly flexible notion is known on the level of the corresponding Euler-Lagrange equations. Our research projects address both fundamental problems in the calculus of variations and applications, e.g. in nonlinear elasticity. The study of

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.

35. Stability Of Equilibria In The Calculus Of Variations Stability of Equilibria in the calculus of variations. For example, the twistedring is described by an isoperimetric calculus of variations problem. http://www.haverford.edu/math/rmanning/stability.html

Stability of Equilibria in the Calculus of Variations Isoperimetric Conjugate Points (cf. Suppose that we have a solution to the Euler-Lagrange equilibrium equations for some calculus of variations functional. This computed equilibrium is a critical point of the functional, but not necessarily a stable local minimum . In the classic theory of the unconstrained calculus of variations, the Jacobi/Morse conjugate point theory is used to classify critical points as local minima or some other type. The number of conjugate points is called the index , and should give the number of downward-turning directions on the (infinite-dimensional) graph of the functional in the neighborhood of the critical point. This conjugate point test can be generalized to isoperimetrically constrained problems. This generalization was done over a century ago for some particular cases by Bolza and others, e.g. for one or two variables and a few constraints. In we have treated the general isoperimetric problem, framing the process in modern functional analytic language. With the appropriate inclusion of projection operators (the projection being onto the space orthogonal to the linearized constraints), the isoperimetric theory can be made to look almost exactly parallel to the unconstrained theory. For example

For example, the problem of finding the closed plane curve of given length that will enclose the greatest area is a type of isoperimetric (equal-perimeter) problem that can be treated by the methods of the variational calculus; the solution to this special case is the circle. Another famous problem is the brachistochrone problem, that of finding the curve along which an object will slide to a point not directly below it in the shortest time; the solution is a cycloid curve (a curve traced out by a fixed point on the circumference of a circle as the circle rolls along a straight line). In general, problems in the calculus of variations involve solving the definite integral (single or multiple) of a function of one or more independent variables, x x , . . . , one or more dependent variables

Silverman Released: November, 2000 ISBN: 0486414485 Paperback Sales Rank: List price: Our price: Calculus of Variations > Customer Reviews: Average Customer Rating: Calculus of Variations > Customer Review #1: A great book by a great mathematician Gelfand was one of the leaders of the great school of mathematics which, somehow, thrived in Soviet Union. I used uncountable times the copy of our library, as the original English edition, in the excellent translation of R. Silvermann, became very hard to find. I put it in the top of the list of books I wanted to buy. Now Dover put it into their catalogue. Great choice. I already ordered my copy! This is the best book on the Calculus of Variations. It contains, for instance, a wonderful treatment of Noethers theorem, hardly to be surpassed. The Hamilton-Jacobi equation is also treated with brilliance and clarity. Gelfand (and Fomin!) developed a style in which the precision of the mathematics does not interfere with the general panorama. The applications are very well selected and perfectly illustrate the theory. A great book, a great mathematician who can write, a great translator, by less than 10 bucks!
