Packing colorings of the corona product of the path Pn and the cycle Cn with an edge K₂
(Işık University Press, 2026-01-01)Given a graph G and a positive integer i, an i-packing in G is a subset X of V (G) such that the distance dG(u, v) between any two distinct vertices u, v ∈ X is greater than i. The packing chromatic number χρ(G) of a graph ... -
Moments of order statistics and k-record values arising from the Beta-Lomax distribution with application
(Işık University Press, 2026-01-01)The concept of k-record values plays a significant role in extreme value theory, which is essential for modeling rare events. In this paper, we focus on k- record values from the Beta-Lomax distribution(BLD), a flexible ... -
Approximations to Caputo fractional derivative with arbitrary kernels and uniform meshes
