### Prerequisites

Some familiarity with the basic objects of algebra, namely, rings, modules, fields, and so on, and with the transcendental extensions of fields (Section 8 of my online notes on Fields and Galois Theory).

An introductory course. In contrast to most such accounts it studies abstract algebraic varieties, and not just subvarieties of affine and projective space. This approach leads more naturally into scheme theory.
