Relation-preserving generalized nonlinear contractions and related fixed point theorems
In this paper, we present some fixed point theorems for generalized nonlinear contractions involving a new pair of auxiliary functions in a metric space endowed with a locally finitely T-transitive binary relation.

ABSTRACT This study examines the interplay between language and social connectedness in forming opinion‐based groups on social media. Drawing on small‐world theory and social identity theory, we propose a dual‐layer approach that combines semantic and network analysis to investigate the dynamics of group formation on X/Twitter during the 2021 COVID‐19 ...

The intent of this paper was to investigate the fixed-point results under relation-theoretic generalized weak contractivity condition employing a pair of auxiliary functions ϕ and ψ verifying appropriate properties.

ABSTRACT Gender and race have received significant philosophical attention recently; they are the paradigm cases of social kinds in most philosophical accounts. I argue for the inclusion of caste as a social kind because it affects the lives of many people, and because it presents itself as an important test case for philosophers of social kinds.

Reachability Relations and the Structure of Transitive Digraphs [PDF]
In this paper we investigate reachability relations on the vertices of digraphs. If $W$ is a walk in a digraph $D$, then the height of $W$ is equal to the number of edges traversed in the direction coinciding with their orientation, minus the number of edges traversed opposite to their orientation.

Simple 3‐Designs of PSL ( 2 , 2 n ) With Block Size 13
ABSTRACT This paper focuses on the investigation of simple 3‐ ( 2 n + 1 , 13 , λ ) designs admitting PSL ( 2 , 2 n ) as an automorphism group. Such designs arise from the orbits of 13‐element subsets under the action of PSL ( 2 , 2 n ) on the projective line X = GF ( 2 n ) ∪ { ∞ }, and any union of these orbits also forms a 3‐design.

The present manuscript is devoted to investigating some existence and uniqueness results on fixed points by employing generalized contractions in the context of metric space endued with a weak class of transitive relation.

Fuzzy T-transitive relations: eigenvectors and generators
After some preliminaries, the set of generators of a generalized equality relation (T-indistinguishability operator) is studied. This set is identified with the set of the eigenvectors of the relation. The relation between the fuzzy and “metric” topologies derived from these equalities is stablished.

ABSTRACT Background Psoriasis is a chronic inflammatory dermatological condition associated with an elevated risk of cardiovascular events (CVEs). Systemic therapies have transformed disease management, but their cardiovascular (CV) safety profiles remain incompletely understood and inconsistently reported.
