| Abstract: | This paper deals mainly with three-dimensional function conditional extremum' s sufficient. The research on three - dimensional function conditional extremum' s sufficient leads to the improvement of the conditions of original theorem principle. The conclusion in a move looser condition is proved by implicit function theorem. |
