Characterizing Invex and Related Properties
B. D. Craven · Kluwer Academic Publishers eBooks · 2006
A characterization of invex , given by Glover and Craven, is extended to functions in abstract spaces. Pseudoinvex for a vector function coincides with invex in a restricted set of directions. The V-invex property of Jeyakumar and Mond is also characterized. Some differentiability properties of the invex scale function are also obtained.
