Solving a class of integral equations via contractive mapping with rational type
( New York Business Global , 2020 , Article)In this paper, using rational type contractive conditions, the existence and uniqueness of common coupled fixed point theorem in the set up of Gb-metric spaces is studied. The derived result cover and generalize some ... -
A new approach in the context of ordered incomplete partial b-metric spaces
( De Gruyter Open Ltd , 2020 , Article)The main purpose of this paper is to find some fixed point results with a new approach, particularly in those cases where the existing literature remains silent. More precisely, we introduce partial completeness, f-orbitally ... -
Some fixed and periodic point results for generalized contractions on partial ordered metric space with applications in metric space
( Boletim da Sociedade Paranaense de Matematica , 2021 , Article)In this paper, we introduce new type of Θ-contraction in termof a self-mapping on a metric space to obtain common fixed point results. Some examples arealso provided to support the validity of our results and concepts ... -

( Boletim da Sociedade Paranaense de Matematica , 2021 , Article)For a set of graphsF, letH(n;F) denote the class of non-bipartiteHamiltonian graphs onnvertices that does not contain any graph ofFas a subgraphandh(n;F) = max{E(G) :G∈H(n;F)}whereE(G) is the number of edges inG.In this ... -
On existence and uniqueness of best proximity points for proximal β-quasi contractive mappings on metric spaces
( Forum-Editrice Universitaria Udinese SRL , 2021 , Article)This paper focus on the study of the generalization of the best proximity point theorems for non-self contractions. In fact we propose two new theorems on the existence and the uniqueness of best proximity points for ... -
Some remarks concerning D∗-metric spaces
( International Scientific Research Publications , 2020 , Article)In [S. Sedghi, N. Shobe, H. Y. Zhou, Fixed Point Theory Appl., 2007 (2007), 13 pages], Sedghi et al. introduced the notion of D∗ -metric space and in [S. Sedghi, N. Shobe, A. Aliouche, Mat. Vesnik, 64 (2012), 258–266] the ... -
Existence of a tripled coincidence point in ordered Gb-metric spaces and applications to a system of integral equations
( Springer , 2013 , Article)In this paper, tripled coincidence points of mappings satisfying some nonlinear contractive conditions in the framework of partially ordered G b-metric spaces are obtained. Our results extend the results of Aydi et al. ... -
Some coincidence point results for generalized (ψ,φ) -weakly contractive mappings in ordered G-metric spaces
( Hindawi Publishing Corporation , 2013 , Article)The aim of this paper is to present some coincidence point results for six mappings satisfying the generalized (ψ,φ) -weakly contractive condition in the framework of partially ordered G-metric spaces. To elucidate our ... -
Coupled coincidence point results for (ψ,φ) -weakly contractive mappings in partially ordered Gb-metric spaces
( Hindawi Publishing Corporation , 2013 , Article)In this paper we present some coupled coincidence point results for (ψ,φ) -weakly contractive mappings in the setup of partially ordered Gb -metric spaces. Our results extend the results of Cho et al. (Fixed Point Theory ... -
b2 -Metric spaces and some fixed point theorems
( Springer International Publishing , 2014 , Article)The aim of this paper is to establish the structure of [InlineEquation not available: see fulltext.]-metric spaces, as a generalization of 2-metric spaces. Some fixed point results for various contractive-type mappings in ... -
Some new results on universal metric spaces
( Chiang Mai University , 2017 , Article)In this paper we establish some common fixed point results for two self-mappings f and g on a universal metric space of dimension n. To prove our results we assume that f is a weakly U-contraction mapping of types Au and ... -
Approximate solutions to the generalized time-fractional ito system
( Forum-Editrice Universitaria Udinese SRL , 2017 , Article)In this work, we consider the time-fractional version of the well-known integrable Ito system to study the effect of its fractional index "memory index". A modified approach of a relatively new method called residual power ... -
Efficient monitoring of coefficient of variation with an application to chemical reactor process
( John Wiley and Sons Ltd , 2021 , Article)Control chart is a useful tool to monitor the performance of the industrial or production processes. Control charts are mostly adopted to detect unfavorable variations in process location (mean) and dispersion (standard ... -
Contributing risk factors of common psychiatric disorders in the Pakistani population
( Springer Science and Business Media Deutschland GmbH , 2022 , Article)With an increasing incidence of psychiatric disorders worldwide, there is a need for a better understanding of the population-specific contributing risk factors that are associated with common psychiatric conditions. This ... -
An improved adaptive EWMA control chart for monitoring time between events with application in health sector
( John Wiley and Sons Ltd , 2023 , Article)Nonconforming events rarely occur in high-quality processes, and the time between events ((Formula presented.)) is likely to be followed by a skewed distribution, such as an exponential distribution. This paper proposes ... -
The use of fast initial response features on the homogeneously weighted moving average chart with estimated parameters under the effect of measurement errors
( John Wiley and Sons Ltd , 2021 , Article)Fast initial response (FIR) features are generally used to improve the sensitivity of memory-type control charts by shrinking time-varying control limits in the earlier stage of the monitoring regime. This paper incorporates ... -
A non-parametric double homogeneously weighted moving average control chart under sign statistic
