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.

Direct methods occupy an important place among the algorithmic methods for finding extrema. 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.

To my ear, “calculus of variations” and “variational calculus” are synonyms. They both refer to the area of mathematics that involves finding an optimal path

In the simple case in which the sample is a slab of thickness d, the total energy per unit area is given by F= Z d=2 Chapter 7 considers the application of variational methods to the study of systems with infinite degrees of freedom, and Chapter 8 deals with direct methods in the calculus of variations. The problems following each chapter were made specially for this English-language edition, and many of them comment further on corresponding parts of the text. Note that variational calculus has been applied to an extensively large number of problems, theories, and formulations most of which could be reexamined in the light of fractional variational calculus.

Variational Calculus 1.1. Introduction The total elastic energy of a sample of a given material is obtained by inte-grating the elastic energy density over the volume of the sample, taking into account the surface contributions. In the simple case in which the sample is a slab of thickness d, the total energy per unit area is given by F= Z d=2

Introduction to variational calculus: Lecture notes1 Edwin Langmann Mathematical Physics, KTH Physics, AlbaNova, SE-106 91 Stockholm, Sweden Abstract I give an informal summary of variational calculus (complementary to the discussion in the course book). Aims (what I hope you will get out of these notes): Fundamental lemma of variational calculus Suppose that H(x) is continuously diﬀerentiable with Z b a H(x)ϕ(x)dx= 0 for every test function ϕ. Then H(x) must be identically zero.
