Global maxima of real-valued functions. (English) Zbl 0577.90068
In this paper, sufficient conditions for a local maximum to be global are discussed. The result is that a real continuously differentiable function f, defined on a subset of $$R^ n$$, under fairly weak conditions, is unimodal if f has a strict local maximum at any stationary point.
