Another generalization of Smith’s determinant. (English) Zbl 0675.10002

The authors consider gcd-closed sets of positive integers, that is, sets \(S=\{x_ 1,x_ 2,...,x_ n\}\) of distinct positive integers such that \((x_ i,x_ j)=1\) for every \(i,j=1,...,n\). They calculate the determinant of the matrix \((s_{ij})\), where \(s_{ij}=(x_ i,x_ j)\), in terms of the Euler totient.
