Some new fixed point theorems for F-metric spaces
, 2020 The present paper introduces some new fixed point and coupled fixed point theorems for F -metric spaces. We introduce a new fixed point theorem, a Kannan type theorem for asymptotically regular operators and basic coupled fixed point theorems along with some

Journal of Function Spaces, Volume 2025, Issue 1, 2025.In this article, we present new results addressing the fixed‐circle and fixed‐disc problems through modification of the multivalued bilateral Jaggi‐type and Dass–Gupta‐type contractions. Furthermore, we demonstrate the application of these theorems to the nonlinear activation mechanism used in neural networks.

An Introduction to C∗‐Algebra‐Valued Metric‐Like Space With Related Applications
Journal of Mathematics, Volume 2025, Issue 1, 2025.It is well‐known that the main objective of metric‐like spaces is to pave way for the development of fixed point results in nonstandard framework, such as in nonsymmetric distance structures, where self‐distances might be nonzero. This objective becomes more achievable when the range set of the distance function is a C∗‐algebra. Unfortunately, the idea

Some fixed and coincidence point theorems for expansive maps in cone metric spaces
, 2012 In this article, we establish some common fixed and common coincidence point theorems for expansive type mappings in the setting of cone metric spaces. Our results extend some known results in metric spaces to cone metric spaces.

Fixed points of generalized contractive mappings of integral type
Fixed Point Theory and Applications, 2014 The aim of this paper is to introduce classes of α-admissible generalized contractive type mappings of integral type and to discuss the existence of fixed points for these mappings in complete metric spaces. Our results improve and generalize fixed point

Proinov contractions and discontinuity at fixed point
Miskolc Mathematical Notes, 2019 In this paper, we show that the contractive definition considered by Proinov [Fixed point theorems in metric spaces, Nonlinear Analysis 64 (2006) 546 557] is strong enough to generate a fixed point but does not force the mapping to be continuous at the ...

Common fixed points of two pairs of mappings satisfying (E.A)-property in partial metric spaces
Journal of Inequalities and Applications, 2014 In this paper, we present common coincidence and common fixed point results for two pairs of mappings that satisfy the (E.A)-property in the setup of partial metric spaces.

Common fixed points of
Fixed Point Theory and Applications, 2011 In this paper, using the setting of a generalized metric space, a unique common fixed point of four R-weakly commuting maps satisfying a generalized contractive condition is obtained. We also present example in support of our result.

Contractive multivalued maps in terms of Q-functions on complete quasimetric spaces
, 2014 In this paper we prove the existence of a fixed point for multivalued maps satisfying a contraction condition in terms of Q-functions, and via Bianchini-Grandolfi gauge functions, for complete T0-quasipseudometric spaces. Our results extend, improve, and

Generalized α-ψ-contractive type mappings of integral type and related fixed point theorems
, 2014 The aim of this paper is to introduce two classes of generalized α-ψ-contractive type mappings of integral type and to analyze the existence of fixed points for these mappings in complete metric spaces. Our results are improved versions of a multitude of
