Calculus of variations

Direct method in the calculus of variations

In mathematics, the direct method in the calculus of variations is a general method for constructing a proof of the existence of a minimizer for a given functional, introduced by Stanisław Zaremba and David Hilbert around 1900. The method relies on methods of functional analysis and topology. As well as being used to prove the existence of a solution, direct methods may be used to compute the solution to desired accuracy.

Algebra - Direct and Inverse Variation [i.e. y is proportional to -something-] (2 of 5)

Visit http://ilectureonline.com for more math and science lectures! One common way to describe a function is through proportionality, that is y is proportional to some algebraic statement. This five part lecture series covers methods of determining what that relationship describing y is.

Ari Stern: Hybrid finite element methods preserving local symmetries and conservation laws

Abstract: Many PDEs arising in physical systems have symmetries and conservation laws that are local in space. However, classical finite element methods are described in terms of spaces of global functions, so it is difficult even to make sense of such local properties. In this talk, I wil
