Abstract:
Let R be a ring and H*R the ring of skew Hurwitz series over R. It is shown that under some additional conditions, H*R has the same triangulating dimension as R. Furthermore, if R is a PWP ring and (R,+) is torsion-free, then so is H*R.
Key words: generalized triangular matrix representation; skew Hurwitz series ring; PWP ring; triangulating dimension
