An application of soft Set and fuzzy soft Set theories to stock management
Taş, Nihal; Özgür, Nihal Yılmaz; Demir, Pelin (2017)We give a new application of both notions of a soft set and of a fuzzy soft set to the effective management of stock-out situation. We construct a model to track the remaining raw materials in stock at the end of the first ... -

Bilateral-type solutions to the fixed-circle problem with rectified linear units application
Taş, Nihal (Scientific Technical Research Council Turkey-Tubitak, 2020)In this paper, we prove new fixed-circle (resp. fixed-disc) results using the bilateral type contractions on a metric space. To do this, we modify some known contractive conditions called the Jaggi-type bilateral contraction ... -
Binary soft set theory
Açıkgöz, Ahu; Taş, Nihal (European Journal Pure, 2016)In this paper, we study the concept of soft sets theory which introduced by Molodtsov [9] and the theory of soft sets which studied by Maji et al. [6]. The authors introduce a binary soft set on two initial universal sets ... -
Caristi-type nonunique fixed-point results and fixed-circle problem on bv(s)-metric spaces
Taş, Nihal; Ege, Özgür (World Scientific Publishing Co., 2023)Fixed-point theory has been comprehensively studied with several methods. One of these methods is to generalize the used metric space such as bv(s)-metric spaces. Another method is to analyze the geometric features of the ... -
Common fixed point results on complex-valued s-metric spaces
Taş, Nihal; Özgür, Nihal Yılmaz (Univ Maragheh, 2020)Banach's contraction principle has been improved and extensively studied on several generalized metric spaces. Recently, complex-valued S-metric spaces have been introduced and studied for this purpose. In this paper, we ... -
Common fixed points of continuous mappings on s-metric spaces
Taş, Nihal; Özgür, Nihal Yılmaz (Maik Nauka/Interperiodica, 2018)The aim of this paper is to obtain some common fixed point results on an S-metric space. For this purpose, we prove new generalized common fixed point theorems using the notions of weak commutation, compatibility, and ... -
Contra g-alpha- and g-beta-preirresolute functions on GTS's
Açıkgöz, Ahu; Taş, Nihal; Sarsak, Mohammad S. (Springer Heidelberg, 2015)In this present paper, we define g-alpha-preirresolute, g-beta-preirresolute, contra g-alpha-preirresolute and contra g-beta-preirresolute functions on generalized topological spaces. We give some examples of this definitions. ... -
Discontinuity at fixed points with applications
Pant, R. P.; Özgür, Nihal Yılmaz; Taş, Nihal (Belgian Mathematical Soc Triomphe, 2019)In this paper, we study new contractive conditions which are strong enough to generate fixed points but which do not force the map to be continuous at fixed points. In this context, we give new results on the fixed-circle ... -
Fixed discs in quasi-metric spaces
Aydi, Hassen; Taş, Nihal; Özgür, Nihal Yılmaz; Mlaiki, Nabil (House Book Science-Casa Cartii Stiinta, 2021)In this paper, we present some results of fixed disc and common fixed disc in quasi-metric spaces, under some very interesting contractions. Obtained results are supported by illustrative examples. -
Fixed point theorems in symmetric controlled m-metric type spaces
Suwais, Khaled; Taş, Nihal; Özgür, Nihal; Mlaiki, Nabil (MDPI, 2023)One of the frequently studied approaches in metric fixed-point theory is the generalization of the used metric space. Under this approach, in this study, we introduce a new extension of M-metric spaces, called controlled ... -
Fixed-circle theorems on G-metric spaces
Kaplan, Elif; Taş, Nihal (Tsing Hua University, 2023)In this paper, we introduce the concept of fixed-circle on G-metric spaces. Using this new concept, we prove some existence and uniqueness theorems for fixed-circles of self-mappings with a geometric interpretation. We ... -
Fixed-disc results on metric spaces

Geometric properties of fixed points and simulation functions
Özgür, Nihal; Taş, Nihal (Tbilisi Centre for Mathematical Sciences, 2023)The main motivation of this paper is to investigate the geometric properties of non unique fixed points of self-mappings via simulation functions. Geometric properties of the fixed point set Fix(f) of a self-mapping f on ... -
Interpolative contractions and discontinuity at fixed point
Taş, Nihal (Universidad Politecnica de Valencia, 2023)In this paper, we investigate new solutions to the Rhoades’ discontinuity problem on the existence of a self-mapping which has a fixed point but is not continuous at the fixed point on metric spaces. To do this, we use the ... -
