The antiadjacency spectrum of some graph operations

Mohammad Farhan, Peter John, Denny Riama Silaban

Published Online: 28 Mar 2026DOI: 10.47974/JDMSC-2346

In this paper: Let Γ = (V, E) be a graph of order η with V = {1, 2, 3, …, η} and E ⊆ [V]2. The antiadjacency matrix of Γ is an η × η matrix where the ij-entry is 1 if ij ∉ E and 0 if otherwise. An antiadjacency matr...

Two types of size Ramsey numbers for matchings of small order

Valentino Vito, Denny Riama Silaban

Published Online: 29 Mar 2022DOI: 10.1080/09720529.2021.2000153

In this paper: For simple graphs G and H, their size Ramsey number is the smallest possible size of F such that for any red-blue coloring of its edges, F contains either a red G or a blue H. Similarly, we can defin...
