A study on the complements of the elements of Z-soft covering based rough lattice and its application
(Işık University Press, 2025-04-01)In this paper, we discuss information system I = (Ω, B) and related Z-soft covering based rough lattices (TS, ∨, ∧) in which ∨ denotes join and ∧ denotes meet. We prove the existence of maximal and minimal elements for ... -
Interval-valued Fermatean fuzzy sets approach for the Spearman rank correlation coefficient
(Işık University Press, 2025-04-01)Correlation is an important concept that can be used to analyze data sets and assist business leaders in gaining valuable insights into the relationships between business outcomes. When conducting a correlation analysis, ... -
Ideal convergence in fuzzy metric spaces
(Işık University Press, 2025-04-01)In this paper, the concepts of K−convergence, K-Cauchy sequences, K*-convergence, and K*-Cauchy sequences in fuzzy metric spaces is proposed. Also, a few fundamental properties of these concepts are investigated. Then, the ... -

Diametral designs arising from hypergraph of some classes of diameter 3 distance regular graphs
(Işık University Press, 2025-04-01)Hypergraph is a graph H = (V, E) where V is the set of vertices and E is the set containing subsets of elements from set V . The elements of set E are called hyperedges and these need not always be of order 2 as in the ... -
Stress-strength model of m-components system in censored data
