Some results on retracts of polynomial rings
Journal of Algebra
In this paper, we first consider the relationship between a polynomial ring B over a Noetherian domain R and the ring of invariants A of a Ga-action on B, when A occurs as a retract of B. Next, we study retracts of a polynomial ring in general and address the questions of D.L. Costa raised in . Finally, we examine the behaviour of ideals and certain properties of rings under retractions.
