Extrema of Multivariate Function and Its Application
摘要
Abstract
It has introduced limit of multivariate function as point P approaches infinity, which conparing the maximum and minimum of a multivariate function in the closed and bounded set as the supremum and infimum of a multivariate function in the gen⁃eral domain of definition. We can got the maximum and minimum by canparing the values of multivariate function among extrema and limits as point P approaches infinity or borders which is not in domian. It has solved a calss of maximum and minimum of multivari⁃ate function.关键词
