Plateau's problem requires finding a surface of minimal area that spans a given contour in space: a solution can often be found by dipping a frame in soapy water. Solutions of boundary value problems for the Laplace equation satisfy the Dirichlet's principle. Many important problems involve functions of several variables. Functions that maximize or minimize functionals may be found. Functionals are often expressed as definite integrals involving functions and their derivatives. One corresponding concept in mechanics is the principle of least/stationary action. The calculus of variations is a field of mathematical analysis that uses variations, which are small changes in functions and functionals, to find maxima and minima of functionals: mappings from a set of functions to the real numbers. A related problem is posed by Fermat's principle: light follows the path of shortest optical length connecting two points, which depends upon the material of the medium. The book contains 20 lectures covering both the theoretical background material as well as an abundant collection of applications. 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.

Top PDF Calculus of variations and advanced calculus dikompilasi oleh. Shilov's 'Mathematical Analysis, A Special Course. Lyusternik, as well as Volume 2 of the well known problem collection by N.
A simple example of such a problem is to find the curve of shortest length connecting two points. In particular, I have consulted the textbooks on the calculus of variations by N.
