The cozero-divisor graph of a ring $R$ is an undirected simple graph whose vertices are the set of all non-zero and non-unit elements of $R$ and two distinct vertices $x$ and $y$ are adjacent if and only if $x \\notin Ry$ and $y \\notin Rx$. The reduced cozero-divisor graph of a ring $R$, is an undirected simple graph whose vertex set is the set of all nontrivial principal ideals of $R$ and two distinct vertices $(a)$ and $(b)$ are adjacent if and only if $(a) \\not\\subset (b)$ and $(b) \\not\\subset (a)$. In this paper, we characterize all classes of finite non-local commutative rings for which the cozero-divisor graph and reduced cozero-divisor graph is of genus two.", "revisions": [ { "version": "v1", "updated": "2022-12-25T13:19:29.000Z" } ], "analyses": { "subjects": [ "05C25" ], "keywords": [ "undirected simple graph", "reduced cozero-divisor graph", "characterization", "distinct vertices", "nontrivial principal ideals" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
