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.

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.

On Boyd-Wong type multivalued contractions and solvability of (k − ~)-Hilfer fractional differential inclusions

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
In this article, we introduce the Boyd-Wong type multivalued contractions and demonstrate that such mappings have a fixed point. Additionally, we look at the solvability of a few (k – ~)-Hilfer initial value fractional differential inclusions of order n −

A construction of fractals via best proximity theory for enriched non-self nonexpansive mappings

Demonstratio Mathematica
The main purpose of this paper is to present a construction of fractals via best proximity theory for b-enriched non-self nonexpansive mappings inspired by the remarkable relationship between the best proximity theory and fractal theory.
