Abstract

Many papers treat the classical problem of the determination function’s extreme points subject to equality type restrictions. The well-known method of Lagrange’s multipliers gives necessary conditions but not sufficient. In this paper, it is shown that in additional hypotesys (like the linearity) the nature of a stationary point remains the same for the restricted function and for the initial one.
