Rings in the near-rings of formal power series

Periodica Mathematica Hungarica, 1991
Let \(A\) be a commutative ring, let \(A[[X]]\) be the ring of formal power series in a single variable \(X\) over some commutative ring \(A\) and let \(A_ +[[X]]\) be the set of formal power series of \(A[[X]]\) with zero constant term, equipped with its structure of a near-ring obtained with addition and composition.

t-closed rings of formal power series

Archiv der Mathematik, 1999
Let \(A \subset B\) be rings. \(A\) is said to be \(t\)-closed in \(B\) if for each \(a \in A\) and \(b \in B\) such that \(b^{2}-ab, b^{3}-ab^{2} \in A\) then \(b \in A\). In this note, the author proves that if \(A\) and \(B\) satisfy that for each \(a \in A\) and \(b \in B\) such that \(ab \in A\) then \(ab^{2} \in A\) and that \(A\) is \(t\)-closed
