| 41. | FEM then uses variational methods from the calculus of variations to approximate a solution by minimizing an associated error function.
|
| 42. | He introduced the method of the critical points at infinity, which is a fundamental step in the calculus of variations.
|
| 43. | In 1904, he published two more papers on the calculus of variations in the " Transactions of the AMS ".
|
| 44. | From 1875 he worked at G�ttingen University, dealing with the subjects of complex analysis, differential geometry and the calculus of variations.
|
| 45. | VSLib " ! provides deformable modeling as part of a library using the constrained optimization techniques of the calculus of variations.
|
| 46. | The calculus of variations and level set methods can be used as a mathematical framework for investigating solutions of the problem.
|
| 47. | In 1981, Kamien and Schwartz published " Dynamic Optimization : Calculus of Variations and Optimal Control in Economics and Management Science ."
|
| 48. | His results agreed with those of Leonhard Euler but were more general and were derived without the means of calculus of variations.
|
| 49. | A basic problem in the calculus of variations is finding the curve between two points that produces this minimal surface of revolution.
|
| 50. | These works devoted to differential calculus and calculus of variations may be considered as the starting point for the researches of Weierstrass.
