Title: Noetherian symbolic Rees algebras-III
Abstract: We shall give examples of ideals whose symbolic Rees algebra is Noetherian. These are the
(1) ideals of space curves of multiplicity 3,
(2) ideals of a finite set of points in projective space,
(3) height one prime ideals in two-dimensional normal local domains.
We shall also discuss necessary and sufficient conditions for the symbolic Rees algebra of a prime ideal to be Noetherian in terms of set-theoretic complete intersections.
