Title:  Lecture I: Cohomology theories and commutative rings

Abstract:   One of the primary goals of algebraic topology is to obtain information about topological spaces X by studying algebraic invariants of X, such as the cohomology H(X; R) with coefficients in a commutative ring R. For many applications, it is useful to consider more exotic invariants given by "extraordinary" cohomology theories (such as K-theory). In this talk, I'll give an informal introduction to the study of extraordinary cohomology theories, emphasizing their algebraic role as generalized commutative rings.
