Quasiconvex, pseudoconvex, and strictly pseudoconvex quadratic functions

Journal of Optimization Theory and Applications, 1981
The purpose of this paper is twofold. Firstly, criteria for quasiconvex and pseudoconvex quadratic functions in nonnegative variables of Cottle, Ferland, and Martos are derived by specializing criteria proved by the author. We do not make use of the concept of positive subdefinite matrices.

On the convexifiability of pseudoconvex C2-functions

Mathematical Programming, 1980
We present new criteria that characterize functions which are convex transformable by a suitable strictly increasing function. We concentrate on twice continuously differentiable pseudoconvex and strictly pseudoconvex functions, and derive conditions which are both necessary and sufficient for these functions to be convex transformable.

Regularity at the boundary for v onQ-pseudoconvex domainsonQ-pseudoconvex domains

Journal d'Analyse Mathématique, 2005
Solvability for\(\bar \partial \) with regularity at the boundary of a domain Ω ⊂⊂ ℂ n for forms of any degreek≥1 was characterized by pseudoconvexity of ϖΩ in [16]. It is proved here thatq-pseudoconvexity suffices to guarantee solvability of forms of degreek≥q+1.

Polynomials and pseudoconvexity

Mathematics Seminar Notes, 1983
The author presents a new notion of pseudoconvexity by means of an Oka's family of analytic discs, and he shows that this definition is equivalent to the standard definition of pseudoconvexity. \(0_ m\) pseudoconvex domain is defined too. His definition of \(0_ m\) pseudoconvex domain is as such that if \(k>m\) then \(0_ k\) pseudoconvex domain is also

Boundary Invariants of Pseudoconvex Domains

The Annals of Mathematics, 1984
Let \(\Omega \subseteq {\mathbb{C}}^ n\) be a smoothly bounded pseudoconvex domain. A notion of multitype of a point \(P\in \partial \Omega\) is introduced. This term is defined in terms of directional derivatives of a defining function for \(\partial \Omega\).
