Seminormal graded rings and weakly normal projective varieties

John V. Leahy and Marie A. Vitulli

International Journal of Mathematics and Mathematical Sciences, 1985, vol. 8, 1-10

Abstract:

This paper is concerned with the seminormality of reduced graded rings and the weak normality of projective varieties. One motivation for this investigation is the study of the procedure of blowing up a non-weakly normal variety along its conductor ideal.
