ESTIMATION OF SOLUTION OF EULER-LAGRANGE EQUATION IN THE BOUNDARY LAYER

Let´s define a ratio between extremals an extremal problem for functional (1) ([1], p.34, formula (1.1.1)) and a problem (2) ([1], p.39, formula (1.2.1)) under

(2)
where the set is defined by next expression:
(3)
Let:
- a function u(t) is the solution of the problem for functional (1),
- a function
is the solution of the problem (2).
From expression (3) it follows
As a result we obtain the estimation
