Twisted Polynomial and Power Series Rings
Bulletin of the Iranian Mathematical Society, 2021Let \(R\) be a commutative ring and \(\mathbb{N}_0\) the ordinary set of nonnegative integers. A function \(t:\mathbb{N}_0\times \mathbb{N}_0\longrightarrow R\) is called a twist function on \(R\) if it satisfies the following three properties for all \(n,m,q\in \mathbb{N}_0\): (i) \(t(0,q)=1\), (ii) \(t(n,m)=t(m,n)\) (iii) \(t(n,m).t(n+m,q)=t(n,m+q).t(

Weak Normalization of Power Series Rings
Canadian Mathematical Bulletin, 1995AbstractIt is proved that if r* is the weak normalization of an integral domain r, then the weak normalization of the power series ring r[[x1,....xn]] is contained in R*[[X1,....Xn]]. Consequently, if R is a weakly normal integral domain, then R[[X1,....Xn]] is also weakly normal.
