A concept of Cohen–Macaulay in codimension t is defined and characterized for arbitrary finitely generated modules and coherent sheaves by Miller, Novik, and Swartz in 2011. Soon after, Haghighi, Yassemi, and Zaare-Nahandi defined and studied CMt s

For a given finite commutative ring R with 1 ≠ 0 , one may associate a graph which is called the total graph of R and it is denoted by T ( R ) . This graph has R as the vertex set and its two distinct vertices x and y are adjacent exactly whenever

Let n be a positive integer and let $$S_n$$ be the set of all nonnegative integers less than n which are relatively prime to n. In this paper, we discuss structural properties of circulant graphs generated by the $$S_n$$ ’s and their complements. I

Let n ≥ 2 be an integer. The graph G ( n ) is obtained by letting all the elements of { 0 , … , n − 1 } to be the vertices and defining distinct vertices x and y to be adjacent if and only if gcd ( x + y , n ) = 1 . In this paper, well-cove

Let R be a finite commutative ring with nonzero identity and denote its Jacobson radical by J(R). The Jacobson graph of R is the graph in which the vertex set is $$R\setminus J(R)$$ , and two distinct vertices x and y are adjacent if and only if $$1-

Let Δ be a simplicial complex and χ be an s-coloring of Δ. Biermann and Van Tuyl have introduced the simplicial complex Δχ. As a corollary of Theorems 5 and 7 in their 2013 article, we obtain that the Stanley–Reisner ring of Δχ over a field
