Abstract:Increasing convex-along-rays functions are defined within an abstract convexity framework. The basic properties of these functions including support sets and subdifferentials are outlined. Applications are provided to unconstrained global optimization using the concept of excess function.
Keywords:Abstract convexity  min-type functions  convex-along-rays functions  subdifferentials  global optimum  excess function
