>can you draw some pictures?
Of? The way I visualize homologies is to start with [math]H^1[/math] as equivalence classes of loops and then generalize to those of cycles [math]\{S^n,M\}[/math]. And then by canonical duality I just visualize cohomologies the same way.

Unless you're doing some weird shit with amplituhedrons you probably won't use algebraic geometry at all. If you meant algebraic topology then there's a very good review article by Mermin that illustrates how cohomology theory can be used to classify defects.
