I plan to cover lots of basic commutative algebra, at the level of AtiyahMacdonald or Miles Reid's UCA, but my emphasis will be on context and historical motivation. The context is the theory of algebraic curves. The historical motivation is Dedekind and Weber's purely algebraic treatment of Riemann surfaces in the language of algebraic number theory. I will cover higher dimensional geometry only as it relates to these topics.
