%0 Journal Article %T The Extreme of a Function Subject to Restraint Conditions %A Catalin Angelo Ioan %A Gina Ioan %J Acta Universitatis Danubius : Oeconomica %D 2011 %I Danubius University %X Many papers treat the classical problem of the determination function¡¯s extreme pointssubject to equality type restrictions. The well-known method of Lagrange¡¯s multipliers givesnecessary conditions but not sufficient. In this paper, it is shown that in additional hypotesys (like thelinearity) the nature of a stationary point remains the same for the restricted function and for theinitial one. %K Lagrange %K multipliers %K extreme %U http://journals.univ-danubius.ro/index.php/oeconomica/article/view/1006/844
