Rees algebra associated with a ring R and an ideal I. In particular, we give a complete
description of the spectrum of every member of the family and describe the localizations at a
prime ideal. Consequently, we are able to characterize the Cohen–Macaulay and
Gorenstein properties, generalizing known results stated in the local case. Moreover, we
study when R (I) a, b is an integral domain, reduced, quasi-Gorenstein, or satisfies Serre's …
