This is a 23-lecture course, with each lecture being around 80 minutes, given online by Kirill Zainoulline. It gives an introduction to algebraic geometry.
A brief overview of commutative algebra: rings and ideals, Nakayama’s Lemma, localization, Krull-dimension, direct-limits, integral dependence. Toward algebraic varieties: Regular functions, algebraic sets, Hilbert’s Nullstellensatz, Zariski topology, ringed spaces, affine and projective varieties. Toward sheaves and group schemes: functors of points, Grothendieck topologies, representable functors, group schemes, tori, Grassmannians, torsors and twisted forms, quadrics and Severi-Brauer varieties.
