The floral scent of Dianthus cruentus Griseb. (Caryophyllaceae)
The genus Dianthus L. (Caryophyllaceae) comprises over 300 species of herbaceous plants that are spread over a vast area, especially in the Mediterranean region. Species of this genus, represented with 38 taxa in the Serbian ...
Synthesis, complete assignment of 1H- and 13C-NMR spectra and antioxidant activity of new azine derivative bearing coumarin moiety
In this research, the synthesis of a new azine derivative with coumarin moiety was performed in three reaction steps, starting from 4-hydroxycoumarin. The first step in synthesis was the acetylation of 4-hydroxycoumarin ...
C-class functions on some fixed point results in ordered partial metric spaces via admissible mappings
(Department of Mathematics and Informatics, Faculty of Sciences, Novi Sad, 2018-06-05)
In this paper, we generalized the results presented in the paper W. Long, S. Khaleghizadeh, P. Salimi, S. Radenović and S. Shukla, Some new fixed point results in partially ordered metric spaces via admissible mappings, ...
Suzuki type fixed point results and applications in partially ordered Sb -metric spaces
(University of Novi Sad, Faculty of Sciences, Department for Mathematics and Informatics, 2019-01-12)
In this paper we give some applications to integral equations as well as homotopy theory via Suzuki type fixed point theorems in partially ordered complete Sb - metric space by using generalized contractive conditions. We ...
On some F−contraction of Piri-Kumam-Dung type mappings in metric spaces
(2020-07-15)
This paper establishes some new results of Piri–Kumam–Dung-type mappings in a complete metric space.Тhe goal was to improve the already published results.
Methods: Using the property of a strictly increasing function as ...
Some remarks on TAC-contractive mappings in b-metric spaces
(Društvo matematičara Srbije, 2018-09-03)
In this paper we complement and improve fixed point results established on
TAC-contractive mappings in the framework of b-metric spaces. Our analysis starts by a
recent paper of Babu and Dula [G. V. R. Babu and T. M. ...
Some New Results for Jaggi-W-Contraction-Type Mappings on b-Metric-like Spaces
(MDPI (Basel, Switzerland), 2021-08-12)
In this article, we generalize, improve, unify and enrich some results for Jaggi-W-contraction-type mappings in the framework of b-metric-like spaces. Our results supplement numerous methods in the existing literature, and ...
New results on F-contractions in complete metric spaces
(MDPI (Basel, Switzerland), 2021-12-21)
The main purpose of this paper is to improve, generalize, unify, extend and enrich the recent results established by Dung and Hang (2015), Piri and Kumam (2014, 2016), and Singh et al. (2018). In our proofs, we only use ...
On Some New Contractive Conditions in Complete Metric Spaces
(MDPI (Basel, Switzerland), 2021-01-07)
One of the main goals of this paper is to obtain new contractive conditions using the method of a strictly increasing mapping F:(0,+∞)→(−∞,+∞). According to the recently obtained results, this was possible (Wardowski’s ...
A new approach to multivalued nonlinear weakly Picard operators
(Springer Nature SharedIt, 2019-11-09)
The notion of nonlinear (Fs,L)-contractive multivalued operators is initiated and some related fixed point results are considered. We also give an example to show the validity of obtained theoretical results. Our results ...
