摘要
In this article, some basic and important properties of spherically convex functions, such as the Lipschitz-continuity, are investigated. It is shown that, under a weaker condition, every family of spherically convex functions is equi-Lipschitzian on each closed spherically convex subset contained in the relative interior of their common domain, and from which a powerful result is derived: the pointwise convergence of a sequence of spherically convex functions implies its uniform convergence on each closed spherically convex subset contained in the relative interior of their common domain.
