The Rees algebra of an ideal is a basic construction that is used for blowing up schemes. There are several ways of generalizing the construction of Rees algebras to more general modules. I will here present a definition along with some related results given in an article by Eisenbud, Huneke and Ulrich. Finally, I will state some new results regarding this Rees algebra and other observations.
