Quasimagic rectangles D. Froncek, K. Paramasivam, A. V. Prajeesh Journal of Combinatorial Designs, 2022 Abstract A quasimagic rectangle is an array with odd and even whose entries are , each appearing exactly once, such that the sum of every row is equal to a constant and the sum of every column is equal to a constant . In this article, we prove the existence of for all possible values of and , when . In addition, if , we prove that the condition is necessary and sufficient for the existence of .
Zero-divisor graph of semisimple group-rings Krishnan Paramasivam, K. Muhammed Sabeel Journal of Algebra and Its Applications, 2022 Let [Formula: see text], [Formula: see text], [Formula: see text] denote the zero-divisor graph, compressed zero-divisor graph and annihilating ideal graph of a commutative ring [Formula: see text], respectively. In this paper, we prove that [Formula: see text] for a semisimple commutative ring [Formula: see text] and represent [Formula: see text] as a generalized join of a finite set of graphs. Further, we study the zero-divisor graph of a semisimple group-ring [Formula: see text] and proved several structural properties of [Formula: see text] and [Formula: see text], where [Formula: see text] is a field with [Formula: see text] elements and [Formula: see text] is a cyclic group with [Formula: see text] elements.
(a,d)-distance antimagicness of disconnected 2-regnlar graphs A. V. Prajeesh, K. Muhammed Sabeel, K. Paramasivam Aip Conference Proceedings, 2021 A distance magic labeling of a graph G on p vertices is a bijection l from the vertex set of G to {1, 2, ···, p} such that for any vertex x of G, the weight of x, wG(x) = ∑v ∈ NG(x) l(v) is a constant. Further, if the weights of vertices of the graph G are in an arithmetic progression of the form a, a + d, …, a + (p – 1)d, then l is an (a, d)-distance antimagic labeling of the graph G. In this paper, we provide a partial solution to the problem on (a, d)-distance antimagicness of disconnected two regular graphs posted by Arumugam and Kamatchi [7].
Maximal super edge-magic graph and its strength T. Sreehari, A. V. Prajeesh, Janitha Kolayil, K. Paramasivam Aip Conference Proceedings, 2021 A (p, q)-graph G is known as super edge-magic if there exists a bijection f from V (G) ∪ E(G) to {1, …, p + q} in such a way that, for any edge uv of G, f (u) + f (v) + f (uv) = c f, is a constant and f (v) ∈ {1, …, p}. Such an f is called a super edge-magic labeling of G and c f is called the super edge-magic constant of G. The strength of a super edge-magic graph G is the minimum of all such c f ’s where the minimum is taken over all super edge-magic labeling f of G. If G is a (p, q)-super edge-magic graph, then we have that q ≤ 2p − 3. Further, any super edge-magic graph G is maximal if q = 2p − 3. In this paper, we give a characterization for any connected triangle-free graph G to attain the lower bound of its super edge-magic strength. Moreover, we determine the strength of certain well-known classes of maximal super edge-magic graphs with girth less than 4.
Note on group distance magicness of product graphs A. V. Prajeesh, K. Paramasivam Contributions to Discrete Mathematics, 2021 In this paper, we provide few results on the group distance magic labeling of lexicographic product and direct product of two graphs. We also prove some necessary conditions for a graph to be group distance magic and provide a characterization for a tree to be group distance magic.
