# Lectures on the Calculus of Variations

270 pages, parution le 01/12/2000 (3eme édition)

## Résumé

Based on lectures delivered at the AMS meeting in 1901, this book describes the progress in calculus of variations made in the last 30 years of the nineteenth century. Among other topics, the author describes the landmark results of Weierstrass on sufficient conditions for the extremum of a functional in terms of the second variation. Also discussed are Kneser's sufficient conditions, Weierstrass's theory of the isoperimetric problem, and Hilbert's theorem on the existence of an extremum of an integral. Although the original book was written nearly 100 years ago, it remains very useful in learning about classical calculus of variations.

Contents

• The first variation of the integral $\int_{x_0}^{x_1}F(x,y,y')dx$
• The second variation of the integral $\int_{x_0}^{x_1}F(x,y,y')dx$
• Sufficient conditions for an extremum of the integral $\int_{x_0}^{x_1}F(x,y,y')dx$
• Weierstrass's theory of the problem in parameter representation
• Kneser's theory
• Weierstrass's theory of the isoperimetric problems
• Hilbert's existence theorem
