7.2. CALCULUS OF VARIATIONS c 2006 Gilbert Strang 7.2 Calculus of Variations One theme of this book is the relation of equations to minimum principles. To minimize P is to solve P 0 = 0. There may be more to it, but that is the main point. For a quadratic P(u) = 1 2 uTKu uTf, there is no di culty in reaching P 0 = Ku f = 0. The matrix K is What is the calculus of variations? It is the solution of optimization problems over functions of 1 or more variables. Some of the applications include optimal control and minimal surfaces. A simple problem of minimal surfaces, for example, is of the form: min u= in @ Z q 1+kruk2dx Now, one of the most basic examples from PDE is the Weak and strong Up: 2. Calculus of Variations Previous: 2.1.4 Brachistochrone Contents Index 2.2 Basic calculus of variations problem The reader has probably observed that the problems of Dido, catenary, and brachistochrone, although different in their physical meaning, all take essentially the same mathematical form. Woodhouse (A Treatise on Isoperimetrical Problems and the Calculus of Variations, 1810) writes (p. 1): "The ordinary questions of maxima and minima were amongst the first that engaged the attention of mathematicians at the time of the invention of the Differential Calculus (1684), three years before the publication of the Principia.

Woodhouse s other writings include a history of the calculus of variations (1810), a treatise on astronomy (1812), and a work on the theory of gravitation, somewhat misnamed Physical Astronomy (1818). In all these works Woodhouse presented the resultsof continental research from the time of Newton up to his own time. BIBLIOGRAPHY I. Original Perhaps the first problem in the calculus of variations was the brachistochrone problem formulated J.

Create Sep 01, 2007 It was in his 1744 book, though, that Euler transformed a set of special cases into a systematic approach to general problems: the calculus of variations was born. Euler coined the term calculus of variations,or variational calculus,based on the notation of Joseph-Louis Lagrange whose work formalised some of the underlying concepts. Isoperimetric Problems. So far we have dealt with boundary conditions of the form y(a) = A, y(b) = B or y(a) = A, y'(b) = B. For some problems the natural BASICS OF CALCULUS OF VARIATIONS MARKUS GRASMAIR 1.

Finally, between 1812 and 1821, he published textbooks on astronomy which took the [1810], ISAAC TODmJNTER [1861] and HERMAN GOLDSTINE [1980] we possess today a fairly comprehensive outline of LAGRAY~E'S main results in the calculus of variations.
