I would like to know a reference to understand what an author means with:

"Let $A$ be a commutative algebra with unit. Regard $A$ as the algebra of functions on an affine variety $M$ (possibly singular). Actually points on $M$ are just ideals in $A$ of codimension one."

My doubt is how to regard $A$ in this way and also how to show the above equivalence with ideals.

    @Andrew Yes, you can assume these hypotheses. I didn't see anything in this link, what should I look for to get an answer?2012-10-06
