Almost Contractions under Binary Relations
Axioms, 2022 After the introduction of almost contraction due to Berinde, the branch of metric fixed point theory has attracted much attention in this direction, and various fixed point results have been proved for almost contractions via different approaches.

Compressed representation of dynamic binary relations with applications [PDF]
Information Systems, 2017 We introduce a dynamic data structure for the compact representation of binary relations R ⊆ A × B . The data structure is a dynamic variant of the k2-tree, a static compact representation that takes advantage of clustering in the binary relation to ...

On binary relations induced from overlap and grouping functions
International Journal of Approximate Reasoning, 2019 In this paper, firstly, we introduce the binary relation ⪯ O derived from an overlap function O. And then, we show that ⪯ O does not satisfy the reflexivity, anti-symmetry and transitivity naturally, and investigate the conditions under which ⪯ O can ...

Partitioned binary relations [PDF]
MATHEMATICA SCANDINAVICA, 2011 We define the category of partitioned binary relations and show that it contains many classical diagram categories, including categories of binary relations, maps, injective maps, partitions, (oriented) Brauer diagrams and (oriented) Temperley-Lieb ...

Set operations over compressed binary relations
Information Systems, 2019 Binary relations are commonly used to represent relationships between real-world objects. Classical representations for binary relations can be very space-consuming when the set of elements is large.

Binary Relations in the Space of Binary Relations. II.
Applied Mathematical Sciences, 2014 This article formulates principles of extension, saturation and convergence, and shows how to implement them. In socio-economic systems, there are "reference groups", with the indicators of which the results of the research and experimentation are ...

Selective Games on Binary Relations [PDF]
Topology and its Applications, 2014 We present a unified approach, based on dominating families in binary relations, for the study of topological properties defined in terms of selection principles and the games associated to them. Among other applications, this general framework allows us

Compressed Dynamic Binary Relations [PDF]
2012 Data Compression Conference, 2012 We introduce a dynamic data structure for the compact representation of binary relations R ? A × B. Apart from checking whether two objects (a, b) ? A × B are related, and listing the objects of B related to some a ? A and vice versa, the structure allows inserting and deleting pairs (a, b) in the relation, as well as modifying the base sets A and B ...

Rough cubic intuitionistic fuzzy soft relation framework for risk identification and hospital selection in breast cancer treatment [PDF]
Scientific ReportsConventional fuzzy or rough set models struggle to capture the ambiguity, hesitancy, and partial information that are frequently present in healthcare decision-making.

Compressed Data Structures for Binary Relations in Practice
IEEE Access, 2020 Binary relations are commonly used in Computer Science for modeling data. In addition to classical representations using matrices or lists, some compressed data structures have recently been proposed to represent binary relations in compact space, such ...
