Common fixed points of compatible mappings [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
In this paper, we present a common fixed point theorem for compatible mappings, which extends the results of Ding, Diviccaro‐Sessa and the third author.

Common fixed point theorem for occasionally weakly compatible mappings in Menger space [PDF]

open access: yesSurveys in Mathematics and its Applications, 2011
The concept of occasionally weakly compatible (shortly, owc) mappings introduced by Al-Thagafi and Shahzad [2], which is more general than the concept of weakly compatible maps.

Quantization and the Resolvent Algebra [PDF]

open access: yes, 2019
We introduce a novel commutative C*-algebra of functions on a symplectic vector space admitting a complex structure, along with a strict deformation quantization that maps a dense subalgebra to the resolvent algebra introduced by Buchholz and Grundling ...

Degrees of compatible L-subsets and compatible mappings

open access: yesKybernetika
Summary: Based on a completely distributive lattice \(L\), degrees of compatible \(L\)-subsets and compatible mappings are introduced in an \(L\)-approximation space and their characterizations are given by four kinds of cut sets of \(L\)-subsets and \(L\)-equivalences, respectively. Besides, some characterizations of compatible mappings and compatible

Some Common Fixed Point Theorems in Generalized Metric Spaces

open access: yesJournal of Mathematics, 2013
First we prove common fixed point theorems for weakly compatible maps which generalize the results of Chen (2012). Secondly, we prove common fixed point theorems using property E.A. along with weakly compatible maps.

Map-compatible decomposition of transport paths

open access: yes, 2023
In the Monge-Kantorovich transport problem, the transport cost is expressed in terms of transport maps or transport plans, which play crucial roles there. A variant of the Monge-Kantorovich problem is the ramified (branching) transport problem that models branching transport systems via transport paths.

Conditionally compatible mappings, non-compatible mappings, faintly compatible mappings and some results on common fixed point in \(C^*\)-algebra valued metric space

open access: yesSahand Communications in Mathematical Analysis
Summary: This manuscript introduces and investigates various types of mappings in the context of a \(C^*\)-algebra valued metric space. These include conditionally compatible, non-compatible, and faintly compatible mappings. Additionally, the manuscript establishes fixed-point results for certain combinations of these mappings.

MRI-compatible pneumatic stimulator for sensorimotor mapping

open access: yesJournal of Neuroscience Methods, 2019
Two major concerns with respect to task-based motor functional magnetic resonance imaging (fMRI) are inadequate participants' performance as well as intra- and inter-subject variability in execution of the motor action.This study validates the use of an MRI-compatible stimulator based on a pneumatic artificial muscle (PAM) for block-design fMRI mapping

Moment maps, symplectomorphism groups and compatible complex structures

open access: yes, 2005
In this paper we apply Donaldson's general moment map framework for the action of a symplectomorphism group on the corresponding space of compatible (almost) complex structures to the case of rational ruled surfaces.

Coinductive Formal Reasoning in Exact Real Arithmetic [PDF]

open access: yes, 2008
In this article we present a method for formally proving the correctness of the lazy algorithms for computing homographic and quadratic transformations -- of which field operations are special cases-- on a representation of real numbers by coinductive ...
