Edit: Not quite a typo at 4:45: for the V function, we have V(I n J)=V(I) u V(J). The vanishing points are unchanged if we replace V(I n J) with V(IJ), but if you get into the scheme game, there's a difference. See links in the comments.
Basic Algebraic Geometry: We define affine varieties over the complex numbers, the Zariski topology on C^n, and the Zariski closure of a subset X in C^n.
Prerequisites: A first year of graduate algebra, but the course was run with advanced undergraduates in mind. Chapter 0 forthcoming, which will give a better idea of the big picture.
