First variation of energy
WebThe amount of energy required to remove an electron from an atom depends on the number of protons in the nucleus of the atom and on the electronic configuration of that atom.

Web8.5 An aside about Kinetic Energy The expectation value of the kinetic energy hTˆi is always positive. This can be shown by an integration by parts in which the first term vanishes provided the wavefunction tends to zero at infinity (which it will for a bound state). In 1D: hTˆi = −¯h 2 2m Z Φ∗ d dx2 Φdx = −¯h2 2m [Φ∗ d dx Φ]∞ WebThe definition of the First Variation - Calculus of Variation. I have the following definition of the functional derivative δ S δ γ, where S is my functional and γ is a curve: where h ( x) is an arbitrary function having the same fixed endpoints as y, ϵ is a small constant, and δ γ = ϵ …
In applied mathematics and the calculus of variations, the first variation of a functional J(y) is defined as the linear functional mapping the function h to where y and h are functions, and ε is a scalar. This is recognizable as the Gateaux derivative of the functional. In a Riemannian manifold M with metric tensor g, the length L of a continuously differentiable curve γ : [a,b] → M is defined by The distance d(p, q) between two points p and q of M is defined as the infimum of the length taken over all continuous, piecewise continuously differentiable curves γ : [a,b] → M such that γ(a) = p and γ(b) = q. In Riemannian geometry, all geodesics are locally distance-minimizing paths, but t…
