Commuting and compatible mappings in digital metric spaces
In this paper, we prove a common fixed point theorem for commuting mappings and some common fixed point theorems for compatible mappings and its variants in digital metric spaces. Furthermore, we give some examples in support of our results.

Common fixed point theorems for compatible mappings
By using a compatibility condition due to Jungck we establish some common fixed point theorems for four mappings on complete and compact metric spaces These results also generalize a theorem of Sharma and Sahu.

Common fixed point theorems for two and three mappings
In this paper, we provide common fixed point theorems for two and three commuting mappings which generalize Darbo’s fixed point theorem. An explicit example is given for illustration.

On ideals of prime rings involving n-skew commuting additive mappings with applications
WOS:000863056600002Let n > 1 be a fixed positive integer and S be a subset of a ring R. A mapping zeta of a ring R into itself is called n-skew-commuting on S if ((x)x(n) + x(n )zeta(x) = 0, for all x is an element of S.

Some Generalizations of Jungck's Fixed Point Theorem
We are going to generalize the Jungck's fixed point theorem for commuting mappings by mean of the concepts of altering distance functions and compatible pair of mappings, as well as, by using contractive inequalities of integral type and contractive ...

A Common Fixed Point Theorem in D*-Metric Spaces
We give some new definitions of D*-metric spaces and we prove a common fixed point theorem for a class of mappings under the condition of weakly commuting mappings in complete D∗-metric spaces.

On Mappings Which Commute with Convolution [PDF]
The symbolDwill be written for the space of indefinitely differentiable functions on the n-dimensional Euclidean spaceRnwhich have compact support andDapos; will denote the space of Schwartz distribution onRn, the topological dual ofD. Except where contrary is explicitly stated, it will be assumed thatD′ is equipped with the strong topology β (D′,D ...

Let \(R\) be a ring and \(S\) a nonempty subset of \(R\). A map \(f\colon S\to R\) is called commuting on \(S\) if \(f(x)x=xf(x)\) for all \(x\in S\). This paper is a wide-ranging and accessible survey dealing with commuting maps and related maps on various classes of rings, including prime and semiprime rings, Banach algebras, and \(C^*\)-algebras ...
