Invexity of quadratic functions and restricted/local invexity

Journal of Information and Optimization Sciences, 1996
Abstract A characterization of invexity properties of quadratic functions is derived and contrasted with existing results on pseudoconvexity. Three different approaches are employed. In the process quadratic functions are used as approximations to C2-functions to prove results on local invexity.

Generalizedb-invex vector valued functions

Journal of Statistics and Management Systems, 2002
Summary: The aim of this paper is to provide some first results regarding to the extension to the vector valued case of the \(b\)-invex functions. Some definitions are given for both the nonsmooth case and the differentiable case; the inclusion relationships among the introduced families of functions are studied and some results regarding to vector ...

Various types of nonsmooth invex functions

Journal of Information and Optimization Sciences, 1996
Abstract The aim of this paper is to consider various proposals for the extension to a nonsmooth setting of the class of invex functions. In particular we consider functions endowed with generalized directional derivatives in the sense of Clarke, Demyanov and Rubinov, Pshenichnyi, Jeyakumar and Ye.
