Journal of Mathematics, Volume 2025, Issue 1, 2025.In this study, we introduce a novel class of mappings called orthogonal extended interpolative enriched Ćirić–Reich–Rus type ψF‐contractions and establish fixed‐point results within the framework of orthogonal complete convex extended b‐metric spaces. The unique fixed point is approximated using a Krasnoselskii‐type iterative method. To demonstrate the

A note on complementarity problem
International Journal of Mathematics and Mathematical Sciences, Volume 21, Issue 3, Page 621-623, 1998., 1998 In this paper we prove a result of complementarity problem where compact condition is somewhat relaxed.

On Almost (α, θρ)‐Contractions on Quasimetric Space and Their Fixed Points
Journal of Mathematics, Volume 2025, Issue 1, 2025.In this paper, we introduce the concept of almost (α, θρ)‐contraction mappings on quasimetric spaces. Then, under certain conditions, we present some fixed‐point results for almost (α, θρ)‐contraction mappings with respect to ω and γ on both left K‐complete and left M‐complete quasimetric spaces.

Some results on invariant approximation
International Journal of Mathematics and Mathematical Sciences, Volume 17, Issue 3, Page 483-487, 1994., 1993 In this paper results on Invariant approximations, extending and unifying earlier results are given. Several interesting results are derived as corollaries.

A characterization of metric completeness
, 1977 A proof is given of a theorem, relevant to fixed-point theory, which implies that a metric space (X, d) is complete if and only if, for each continuous function h: X -* R bounded below on X, there is a point x0 such that h(xo) h(x) d(xn, x) > 0 ...

CONTINUITY OF THE TYCHONOFF FUNCTOR τ [PDF]
, 1990 Let C be a class of the inverse systems X = {Xλ, fαβ,A}. We say that a functor F is C-continuous if F(limX) is homeomorphic with lim F(X). In the present paper the continuity of Tychonoff functor τ is investigated.

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015 In this paper, by combining a modified extragradient scheme with the viscosity approximation technique, an iterative scheme is developed for computing the common element of the set of fixed points of a sequence of asymptotically nonexpansive mappings and

A multivalued version of Krasnoselskii’s theorem in generalized Banach spaces
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014 The purpose of this paper is to extend Krasnoselskii’s fixed point theorem to the case of generalized Banach spaces for multivalued operators. As application, we will give an existence result for a system of Fredholm-Volterra type differential inclusions.

Ishikawa iterative process for strongly pseudocontractive operators in arbitrary Banach spaces [PDF]
, 2003 In this note we give a correction to the main result of Zhou in [14] on the convergence of the Ishikawa iteration process to a unique fixed point of a strongly pseudocontractive operator in arbitrary real Banach spaces.
