abstract:
Using compact expressions for optimal and varied trajectories based on the 
representation of the Cauchy problem solution as evolution system of functions 
of initial values, a simple analytic proof of Pontryagin's Maximum Principle for 
fixed endpoints is obtained. Some non-standard problems of optimal control 
theory are considered shortly, too.
