When is the product of two ideals equal to their intersection?
up vote 20 down vote favorite
Consider a ring $A$ and an affine scheme $X=SpecA$ . Given two ideals $I$ and $J$ and their associated subschemes $V(I)$ and $V(J)$, we know that the intersection $I\cap J$ corresponds to the union
$V(I\cap J)=V(I)\cup V(J)$.

13.1 Newton's Method
This method, as just noted, consists of iterating the process of setting the linear approximation of f to 0 to improve guesses at the solution to f = 0.

Using Power Series to solve Non-Homog. DE
The equation is y''-4xy'-4y= e^x, assuming that y=(sigma from 0 to infinity) c_nx^n, a=0
So I did the substitution and found the recurrence term to be
