On the Necessity of the Sufficient Conditions in Cone-Constrained Vector Optimization [PDF]

open access: yes, 2014
The object of investigation in this paper are vector nonlinear programming problems with cone constraints. We introduce the notion of a Fritz John pseudoinvex cone-constrained vector problem.

Geometry of analytic continuation on complex manifolds – history, survey, and report

open access: yesComplex Manifolds
Beginning with the state of art around 1953, solutions of the Levi problem on complex manifolds will be recalled at first up to Takayama’s result in 1998.

Volume functionals on pseudoconvex hypersurfaces

open access: yesInternational Journal of Mathematics
The focus of this paper is on a volume form defined on a pseudoconvex hypersurface [Formula: see text] in a complex Calabi–Yau manifold (that is, a complex [Formula: see text]-manifold with a nowhere-vanishing holomorphic [Formula: see text]-form). We begin by defining this volume form and observing that it can be viewed as a generalization of the ...

Holomorphic L 2 Functions on Coverings of Pseudoconvex Manifolds [PDF]

open access: yesGeometric And Functional Analysis, 1998
Let \(\widetilde M\) be a complex manifold, \(\overline {M}= M\cup bM\subset\widetilde M\) be a closed submanifold of \(\widetilde M\) with smooth boundary, \(\dim_{\mathbb C}\widetilde M = \dim_{\mathbb C}M\). Let \(\Gamma\) be a discrete group acting freely and holomorphically on \(\widetilde M\) such that \(\Gamma\) invariates \(\overline {M}\) and \

On functional representation of locally m‐pseudoconvex algebras [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1999
Functional representation of a topological algebra (A, T) has been studied in many papers under various assumptions for the topology T on A. Usually the image of the Gelfand map has been equipped with the compact‐open topology. This leads, in several cases, to such kind of difficulties as, for instance, that the Gelfand map is not necessarily ...

Fractional Optimization Problems

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2014
We consider fractional maximization and minimization problems with an arbitrary feasible set, with a convex function in the numerator, and with a concave function in the denominator. These problems have many applications in economics and engineering.

Fefferman's mapping theorem on almost complex manifolds

open access: yes, 2004
We give a necessary and sufficient condition for the smooth extension of a diffeomorphism between smooth strictly pseudoconvex domains in four real dimensional almost complex manifolds.
