Quasi-convex univalent functions [PDF]
International Journal of Mathematics and Mathematical Sciences, 1980 In this paper, a new class of normalized univalent functions is introduced. The properties of this class and its relationship with some other subclasses of univalent functions are studied. The functions in this class are close-to-convex.

On quasi-convex functions and related topics [PDF]
International Journal of Mathematics and Mathematical Sciences, 1987 Let S be the class of functions f which are analytic and univalent in the unit disc E with f(0)=0, f′(0)=1. Let C, S* and K be the classes of convex, starlike and close-to-convex functions respectively.

Some Quantum Estimates of Hermite-Hadamard Inequalities for Quasi-Convex Functions
Mathematics, 2019 In this paper, we develop some quantum estimates of Hermite-Hadamard type inequalities for quasi-convex functions. In some special cases, these quantum estimates reduce to the known results.

Quasi Semi and Pseudo Semi (p,E)-Convexity in Non-Linear Optimization Programming
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2023 The class of quasi semi -convex functions and pseudo semi -convex functions are presented in this paper by combining the class of -convex functions with the class of quasi semi -convex functions and pseudo semi -convex functions, respectively.

Krein’s Theorem in the Context of Topological Abelian Groups
Axioms, 2022 A topological abelian group G is said to have the quasi-convex compactness property (briefly, qcp) if the quasi-convex hull of every compact subset of G is again compact.

Open Physics, 2021 In the present study, two new classes of convex functions are established with the aid of Raina’s function, which is known as the ψ-s-convex and ψ-quasi-convex functions. As a result, some refinements of the Hermite–Hadamard (ℋℋ{\mathcal{ {\mathcal H} {\

Quasi-Herglotz functions and convex optimization [PDF]
Royal Society Open Science, 2020 We introduce the set of quasi-Herglotz functions and demonstrate that it has properties useful in the modelling of non-passive systems. The linear space of quasi-Herglotz functions constitutes a natural extension of the convex cone of Herglotz functions.

An Algorithm for Detecting Directional Quasi-Convexity [PDF]
BIT Numerical Mathematics, 2004 This paper is concerned with the practical verification of the so called directional quasi-convexity (DQC) property which is a sufficient condition of Nekhoroshev stability of Hamiltonian systems around equilibrium points. After starting with a clear motivation the stability problem under consideration, the truncated fourth-order Birkhoff normal form ...
