... zero-divisor graph of R, Γ (Z*(𝑅)) usually written as 𝛤(𝑅), is the graph in which each element of Z*(𝑅) is a vertex and two distinct vertices x and y are adjacent if and only if 𝑥𝑦 = 0. In this paper we present a ... See full document

... Abstract—In this paper, we consider the factorization ap- proach to control systems with plants admitting coprime fac- torizations. Further, the set of stable causal transfer functions is a general commutative ... See full document

... We suppose that S −→ R −→ Q is a cofibre sequence of commutative algebras with a map to k, and we now consider the Gorenstein ascent question. When does the fact that S is Gorenstein imply that R is Gorenstein? It ... See full document
