    On strong \((\alpha ,\mathbb F)\)-convexity (English)
    0 references
    The characterization of strong \((\alpha, \mathbb{F})\)-convexity, where \(\mathbb{F}\) is a subfield of \(\mathbb{R}\), is obtained by using the notion of \(\mathbb{F}\)-directionally differentiable function and \(\mathbb{F}\)-sublinear map. Moreover, the properties of the \(\mathbb{F}\)-subdifferential of strongly \((\alpha, \mathbb{F})\)-convex function are given.
