# Variational calculus supplies the analytic bridge linking ancient conjectures concerning an ideal universe with modern demands for optimal control of operating systems. It was instrumental in formulating variational principles of mechanics and physics and continues to supply insight into the relationship between these principles and their Euler-Lagrange systems of differential equations.

One of the basic problems in the calculus of variation is (P) minv∈VE(v). That is, we seek a u ∈ V : E(u) ≤ E(v) for all v ∈ V. Euler equation. Let u ∈ V be a solution of (P) and assume additionally u ∈ C2(a,b), then d dx fu0(x,u(x),u0(x)) = fu(x,u(x),u0(x)) in (a,b).

Set-Valued and Variational Analysis, 19, 23 Svetitsky's notes to give some intuition on how we come on variation calculus from regular calculus with a bunch of examples along the way. Eventually we will Lectures by Denis Dalidovich on Variational Calculus and Gaussian Integrals (followed by few more lectures on different topics): http://pirsa.org/ This is a home page of a course on the calculus of variations.

Aims (what I hope you will get out of these notes): 2021-04-13 · Calculus of Variations. A branch of mathematics that is a sort of generalization of calculus. Calculus of variations seeks to find the path, curve, surface, etc., for which a given function has a stationary value (which, in physical problems, is usually a minimum or maximum ). In science and especially in mathematical studies, a variational principle is one that enables a problem to be solved using calculus of variations, which concerns finding such functions which optimize the values of quantities that depend upon those functions. In this video, I introduce the subject of Variational Calculus/Calculus of Variations. I describe the purpose of Variational Calculus and give some examples 2017-11-30 · Variational calculus – sometimes called secondary calculus – is a version of differential calculus that deals with local extremization of nonlinear functionals: extremization of differentiable functions on non-finite dimensional spaces such as mapping spaces, spaces of sections and hence spaces of histories of fields in field theory.

This is simple and it satis es the boundary conditions.

### carries ordinary calculus into the calculus of variations. We do it in several steps: 1. One-dimensional problems P(u) = R F(u;u0)dx, not necessarily quadratic 2. Constraints, not necessarily linear, with their Lagrange multipliers 3. Two-dimensional problems P(u) = RR F(u;ux;uy)dxdy 4. Time-dependent equations in which u0 = du=dt.

After that, going from two to three was just more algebra and more complicated pictures.

All this is to set the stage calculus of variations, branch of mathematics mathematics, deductive study of numbers, geometry, and various abstract constructs, or structures; the latter often "abstract" the features common to several models derived from the empirical, or applied, sciences, although many emerge from purely mathematical or logical calculus of variations has been intimately connected with the theory of di eren-tial equations; in particular, the theory of boundary value problems. Sometimes a variational problem leads to a di erential equation that can be solved, and this gives the desired optimal solution.
