Pfaff-Birkhoff原理的半固定端点条件

THE SEMI-FIXED END-POINT CONDITIONS IN PFAFF——BIRKHOOF PRINCIPLE

  • 摘要: 从3个方面论证Pfaff——Birkhoff 原理的端点条件不是固定的,而是半固定的,对端点非固定部分导出了相应的自然端点条件,并给出它的一般形式。

     

    Abstract: In this paper, based on three aspects, it is shown that in Pfaff-Birkhoof principle, the end-point conditions are not fixed, but semi-fixed. The corresponding natural end-point conditions for non-fixed variables at the end-points are deduced, and the general forms of the conditions are given.
