Presic Type Fixed Point Theorem for Four Maps in Metric Spaces

Journal of Mathematics, 2016
We obtained a Presic type fixed point theorem for two pairs of jointly 2k-weakly compatible maps in metric spaces. We also have given an example to illustrate our main theorem.

On variational eigenvalue approximation of semidefinite operators

, 2011
Eigenvalue problems for semidefinite operators with infinite dimensional kernels appear for instance in electromagnetics. Variational discretizations with edge elements have long been analyzed in terms of a discrete compactness property.

Weakly Compatible Maps in Complex Valued G- Metric Spaces [PDF]

International Journal of Computer Applications, 2014
In this paper, we introduce the notion of complex valued Gmetric spaces and prove a common fixed point theorem for weakly compatible maps in this newly defined spaces. Mathematics Subject Classification (2000): 47H10, 54H25.

KDM7A and KDM1A inhibition suppresses tumour promoting pathways in prostate cancer

Molecular Oncology, EarlyView.
Treatment resistance is a major challenge for patients with advanced prostate cancer. This study examined an alternative approach to target the major prostate cancer‐promoting pathway by targeting epigenetic factors, whose levels are higher in tumours.

New Fixed Point Results in Neutrosophic Metric Spaces [PDF]

Neutrosophic Sets and Systems
In this manuscript, we give the generalization of banach’s, Kannan’s and Chatterjee’s fixed Point theorems in neutrosophic metric spaces by using new (TS-IF⍺) contractive mappings.

Homologies of Algebraic Structures via Braidings and Quantum Shuffles [PDF]

, 2012
In this paper we construct "structural" pre-braidings characterizing different algebraic structures: a rack, an associative algebra, a Leibniz algebra and their representations. Some of these pre-braidings seem original.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

A common fixed point result for two pairs of maps in b-metric spaces without (E.A.)-property [PDF]

Mathematica Moravica, 2019
In this paper, we investigate a common fixed point problem for two pairs {f, S} and {g, T} of weakly compatible selfmaps of a complete b-metric (X, d; s), satisfying a contractive condition of Ćirić type.

Some common fixed point theorems for weakly compatible mappings

Journal of Mathematical Analysis and Applications, 2006
The authors modify the definition of weakly compatibility for non self mappings. They generalize the theorem of Rhoades [\textit{B. E. Rhoades}, Int. J. Math. Math. Sci. 20, 9--12 (1997; Zbl 0882.47038)]. To accomplish this the authors improve the method of proof used by Rhoades [loc. cit.] and Ahmed and Rhoades [\textit{A. Ahmed, B. E.

FIXED POINTS OF OCCASIONALLY WEAKLY COMPATIBLE MAPPINGS USING IMPLICIT RELATION [PDF]

Communications of the Korean Mathematical Society, 2012
In this paper, we prove common fixed point theorems for families of occasionally weakly compatible mappings in Menger spaces using implicit relation. Our results extend and generalize the results of Altun and Turkoglu [9] in the sense that the concept of occasionally weakly compatible maps is the most general among all the commutativity concepts.
