On Some New Results in Graphical Rectangular b-Metric Spaces
(MDPI (Basel, Switzerland), 2020-04-01)In this paper, we provide an approach to establish the Banach contraction principle (for the case λ∈[0,1)) , Edelstein, Reich, and Meir–Keeler type contractions in the context of graphical rectangular b-metric space. The ... -
On Recent Results Concerning F-Contraction in Generalized Metric Spaces
(MDPI (Basel, Switzerland), 2020-05-11)In this manuscript we discuss, consider, generalize, improve and unify several recent results for so-called F-contraction-type mappings in the framework of complete metric spaces. We also introduce (φ,F) -weak contraction ... -
On F-Contractions for Weak α-Admissible Mappings in Metric-Like Spaces
(MDPI (Basel, Switzerland), 2020-09-21)In the paper, we consider some fixed point results of F-contractions for triangular α-admissible and triangular weak α-admissible mappings in metric-like spaces. The results on F-contraction type mappings in the context ... -
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 ... -
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 ... -
The second mean value theorem for complex line integral
In real iterations, several types of mean value theorems for definite integrals are used. In complex domain, we cannot specifically formulate the mean value theorem of a particular complex line integral (L) ∫f(z)dz , since ... -
Complex homogeneous differential equation of first and second order through iterations
The theory of complex differential equations represents an important mathematical discipline both from the theoretical point of view and from numerous applications. Its development was equally encouraged by mathematicians, ... -
Zero search method for complex oscillating equation directly by direction
The problem of location of the zero solution of the second order complex oscillator equation for the given analytic function is unlikely to be completely solved. Therefore, estimates have long been resorted to. The easiest ... -
Number of zero solutions of some canonical complex differential equations of second order with variable coefficient
By solving the frequency function equation only a small number of complex equations of the second order oscillations can be solved. The simplest way is to observe canonical complex differential equations with constant ... -
Analysis of ecological territorial risk by methods of multidimensional statistics
В работе рассмотрены водные экосистемы как элементы единой социально природно-техногенной системы, предлагаемой для решения задач управления развитием промышленных территорий. Для оценки территориальных рисков водных ... -
Some recent fixed point results of F-contractive mappings in metric space
The opinion is that the most important result in the metrical theory of fixed points is the famous Banach contraction principle from 1922. It has been generalized and extended in several directions. One of the most ... -
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 ... -
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 ... -

Radenović and S. Shukla, Some new fixed point results in partially ordered metric spaces via admissible mappings, ... -
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. ... -

Application of software packages for demonstration of physics experiments
(2018-10-07)Veliki broj osnovnih i srednjih škola u Republici Srbiji nije adekvatno opremeljen za izvođenje nastave fizike. Tu se pre svega misli na nedovoljnu opremljenost kabineta za nastavu fizike, kojima često nedostaje oprema za ... -
