🌿Algebraic Geometry

What do you learn in Algebraic Geometry

Algebraic Geometry combines algebra and geometry to study geometric objects defined by polynomial equations. You'll explore affine and projective varieties, sheaf theory, and schemes. The course covers intersection theory, cohomology, and algebraic curves. You'll also delve into more advanced topics like Hilbert schemes and moduli spaces.

Is Algebraic Geometry hard?

Algebraic Geometry has a reputation for being pretty tough. It's not just the math that's challenging, but also the abstract concepts and the way they all connect. You'll need a solid foundation in abstract algebra and some topology to really get it. That said, if you put in the work and ask for help when you need it, it's totally doable.
