Maybe I have not really understood what does it mean localization of a ring or a module at a prime ideal. I know the definition but i cannot really use it in the practice.
If I have an ideal, in my case $$I=\left(x^2+y^2-yz,xyz-z,y(y-z)(yz-1)\right),$$ what does it mean in the practice $I\mathbb{C}[x,y,z]_{(x,y)}$?
Thank you.
