Second-order normal vectors to a convex epigraph
Published online by Cambridge University Press: 17 April 2009
Abstract
The second–order behaviour of a nonsmooth convex function f is reflected by the so–called second–order subdifferential mapping ∂2f. This mathematical object has been intensively studied in recent years. Here we study ∂2f in connection with the geometric concept of “second-order normal vector” to the epigraph of f.
