Fixed point results of weakly contraction mappings in partially ordered b-metric spaces
BMC Research Notes, 2022 Objectives We explored the results of fixed point, coincidence point and coupled coincidence point for the mappings in an ordered metric spaces. Our results generalized and extended the well-known results in the literature.

Coincidence points in uniform spaces [PDF]
International Journal of Mathematics and Mathematical Sciences, 1992 Summary: We give a coincidence point theorem in sequentially complete Hausdorff uniform spaces. Our result reduces to a result of \textit{S. P. Acharya} [Yokohama Math. J. 22, 105-116 (1974; Zbl 0295.54058)].

Axioms, 2023 In this paper, we prove a coincidence point result for a pair of mappings satisfying Edelstein-type contractive condition on fuzzy metric spaces. We describe the equilibrium of a simple demand–supply model of a dynamic market by the coincidence point of ...

Fixed point results for weak contractions in partially ordered b-metric space
BMC Research Notes, 2021 Objectives We explore the existence of a fixed point as well as the uniqueness of a mapping in an ordered b-metric space using a generalized $$({\check{\psi }}, \hat{\eta })$$ ( ψ ˇ , η ^ ) -weak contraction.

Some results on coincidence points [PDF]
Bulletin of the Australian Mathematical Society, 1999 In this paper we prove some coincidence point theorems for nonself single-valued and multivalued maps satisfying a nonexpansive condition. These extend fixed point theorems for multivalued maps of a number of authors.

BMC Research Notes, 2020 Objectives The aim of this paper is to establish some fixed point, coincidence point and, coupled coincidence and coupled common fixed point results for generalized $$(\phi , \psi )$$ ( ϕ , ψ ) -contractive mappings in partially ordered b-metric spaces ...

Note on KKM maps and applications
Fixed Point Theory and Applications, 2006 We apply the KKM technique to study fixed point theory, minimax inequality and coincidence theorem. Some new results on Fan-Browder fixed point theorem, Fan's minimax theorem and coincidence theorem are obtained.

On coincidence points for vector mappings [PDF]
Russian Mathematics, 2016 For mappings acting in the product of metric spaces we propose a concept of vector covering. This concept is a natural extension of the notion of covering formappings inmetric spaces. The statements on the solvability of systems of operator equations are proved for the case when the left-hand side of an equation is a value of a vector covering mapping ...

Algebraic Coincidence Periods Of Self – Maps Of A Rational Exterior Space Of Rank 2
مجلة بغداد للعلوم, 2010 Let f and g be a self – maps of a rational exterior space . A natural number m is called a minimal coincidence period of maps f and g if f^m and g^m have a coincidence point which is not coincidence by any earlier iterates.

Coincidence invariants and higher Reidemeister traces [PDF]
, 2015 The Lefschetz number and fixed point index can be thought of as two different descriptions of the same invariant. The Lefschetz number is algebraic and defined using homology.
