Quantum Physics Pampered Chef Paintball Guns Cell Phone Reviews ... Science Articles Calculus of variations Online Encyclopedia 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

The Calculus of Variations in Maple 8 Introduction The new VariationalCalculus package provides routines for solving problems in the calculus of variations, which studies nature's most "efficient" curves and surfaces. Classical problems from the calculus of variations include: Find the shortest path between two points on a 3-D surface, such as a cone (a geodesic problem). Shape a ramp between two heights such that a ball rolling down it reaches the bottom in minimum time (the Brachistochrone problem). Find the shape of a soap film having minimum surface area spanning a given wire frame. Such problems can often be solved with the Euler-Lagrange equation, which generalizes the Lagrange Multiplier Theorem for minimizing functions of real variables subject to constraints. The Euler-Lagrange equation is easy to write down in general but notoriously difficult to write down and solve for most practical problems. The VariationalCalculus package automates the construction and analysis of the Euler-Lagrange equation. Example: The Brachistochrone Problem The Brachistochrone problem can be stated as follows: Given two endpoints in the plane, find the curve y(x) between them such that a ball of unit mass rolls along the curve under the influence of gravity in minimum time.

The discussion of the variational (bi)complex is set up in terms of a flat connection in the jet bundle. We extend it to supercase using a particular new class of forms. We establish relation of the complex of variational derivatives and the variational complex. Certain calculus of Lagrangians of multidimensional paths is developed. It is shown how covariant Lagrangians of higher order can be used to represent characteristic classes.

To appriciate the material you really should have a year of "advanced calculus" also called "intro. real analysis" at some places. This means the formalities of limits, continuity, derivatives, integration and series. This will prepare you to understand and work through the proofs in the text. The problems are nice since they are varied (computational, physics, and proofs) and they do come with many answers and some hints, but you might find that having a mechanics book at your side motivates some of the problems.

Actually, it turns out that the text itself was written some time ago, but dont let you be put off by that - this book is very scholarly and you really will be enlightened by it. Now, where do you begin? Usually at University, I guess, this subject is treated in a way that makes most folks think that just about all "Calculus of Variations" problems can be solved with the Euler Lagrange equation, and from there on, you just have to solve the resulting differential equation. And I guess thats sometimes possible. But in the real world, sometimes you end up with that equation simply not working, and your problem is more messy and not expressible using "nice" functions. Now, this is where this book begins. We start by looking at "sufficient" and "necessary" conditions for solutions - and these are not the same things! This at least allows you to work out whether a solution is there, for goodness sake, before you waste time trying to find it.

Calculus of Variations Lecture (starts April 23) Tuesday room 48/582 Thursday room 48/582 Handwritten lecture notes can be found in the library. Brief Summary: The purpose of the course is to demonstrate the beauty and power of variational methods in solving many physical and geometrical problems. The course will give a self contained introduction to the basic variational concepts. Here are some keywords: first variation, Gateaux and Frechet derivatives, fundamental lemma, Euler Lagrange equations, constrained variational problems, Emmy Noether's theorem, second variation, convexity, Legendre transformation, Hamiltonian formulation, Hamilton Jacoby theory, weak lower semicontinuous functionals, existence theorems, regularity results, and many many examples. Here is an example from the theory of capillary surfaces: The result of such a calculation can be seen in the following figure where the capillary surface has been calculated for three different straw diameters. Here is an example from the theory of thin films: If you take a wire hoop, bend it, and put it into soap liquid, you will observe a soap film in your wire frame once you remove it from the liquid. The shape of this surface is dictated again by the principle of least surface energy (it is surface of minimal area, i.e. a
