Quasidifferentiability of nonsmooth quasiconvex functions

Optimization, 1993
The paper deals with nonsmooth quasiconvex functions and develops a quasidifferential analysis for this class of functions. Therefore, in terms of sub and superdifferentials, first order approximations of the functions are derived, optimality conditions are stated and directions of descent (either simple feasible or of steepest descent) are determined.

Quasiconvex functions with subquadratic growth

Proceedings of the Royal Society of London. Series A: Mathematical and Physical Sciences, 1991
Abstract We establish the existence of quasiconvex functions which are not convex and which have subquadratic grow that infinity.

Directional derivatives of quasiconvex functionals

Journal of Soviet Mathematics, 1988
We show that a directional derivative of a quasiconvex functional is also a quasiconvex functional. In this connection we study properties of quasiconvex and positively homogeneous functionals.
