Zbigniew Bartosiewicz, Natalia Martins, Delfim F. M. Torres

摘要:

时间尺度上变分法的基本问题涉及满足给定边界条件的所有轨迹上的δ积分的最小化。本文证明了时间尺度上变分问题最优轨线的第二个欧拉-拉格朗日最优性最优性条件。作为主要结果的一个应用例子,我们对最近在[J. Math. Anal. 342(2008),no. 2,1220-1226]。

英文摘要:

The fundamental problem of the calculus of variations on time scales concerns the minimization of a delta-integral over all trajectories satisfying given boundary conditions. In this paper we prove the second Euler-Lagrange necessary optimality condition for optimal trajectories of variational problems on time scales. As an example of application of the main result, we give an alternative and simpler proof to the Noether theorem on time scales recently obtained in [J. Math. Anal. Appl. 342 (2008), no. 2, 1220-1226].
