The bundle formulation of euler -lagrange equations

الملخص EN

This paper is about global geometrical interpretation of Euler – Lagrange's equations for physical fields in fiber bundle space .

It gives a freecoordinate description of Euler – Lagrange's equations .

The fiber bundle description is considered to be appropriate for all possible fields of nature .
