Finding the extreme efficient solutions of multi-objective pseudo-convex programming problem [PDF]

AUT Journal of Mathematics and Computing
In this paper, we present two methods to find the strictly efficient and weakly efficient points of multi-objective programming (MOP) problems in which their objective functions are pseudo-convex and their feasible sets are polyhedrons.

A New Globally Convergent Self-Scaling Vm Algorithm for Convex and Nonconvex Optimization [PDF]

Kirkuk Journal of Science, 2011
In unconstrained optimization, the original quasi-Newton condition where is the difference of the gradients at two successive iterations. Li and Fukushima proposed a modified BFGS methods based on a new Quasi –Newton equation where , where is a

Duality of locally quasi-convex convergence groups

Applied General Topology, 2021
In the realm of the convergence spaces, the generalisation of topological groups is the convergence groups, and the corresponding extension of the Pontryagin duality is the continuous duality.

Quasi-convex and Q-class functions

Journal of Mathematical Inequalities, 2023
Summary: Convex functions and their variants have played a significant role in the literature. In this article, we investigate two important related classes, namely quasi-convex and \(Q\)-class functions. We will show that these two classes satisfy similar but different properties as those fulfilled by convex functions.

ON INEQUALITIES RELATED TO SOME QUASI-CONVEX FUNCTIONS

Проблемы анализа, 2015
Estimations of errors in inequalities related to some quasi-convex functions in literature are simplified. Two new general inequalities for functions whose n-th derivatives for any positive integer n in absolute values are quasi-convex have been ...

Smooth K-groups for Monoid Algebras and K-regularity

Mathematics, 2015
The isomorphism of Karoubi-Villamayor K-groups with smooth K-groups for monoid algebras over quasi stable locally convex algebras is established. We prove that the Quillen K-groups are isomorphic to smooth K-groups for monoid algebras over quasi-stable ...

A note on convex functions

International Journal of Mathematics and Mathematical Sciences, 1999
In this paper, we give two weak conditions for a lower semi-continuous function on the n-dimensional Euclidean space Rn to be a convex function. We also present some results for convex functions, strictly convex functions, and quasi-convex functions.

Quasi-convexity and shrinkwrapping [PDF]

Algebraic & Geometric Topology, 2009
Let \(S\) be a closed surface of genus \(>1\), \(N\) be an oriented hyperbolic 3-manifold and \(j :S\rightarrow N\) be a \(\pi_1\)-injective map. Let us denote by \(C(B,j)\) the set of homotopy classes of noncontractible simple loops \(\alpha\) where \(j(\alpha)\) has a representative of length \(\leq B\) in \(N\).
