Abstract

It is proved that a commutative domain RR is ωω-Euclidean if and only if the ring of formal Laurent series over RR is ωω-Euclidean domain. It is also proved that every singular matrice over ring of formal Laurent series RXRX are products of idempotent matrices if RR is ωω-Euclidean domain.
