Title: Introduction to Free Resolutions

Abstract: Given a ring R and an R-module M, a free resolution of M is an approximation of M in terms of the simplest kind of module: namely, free modules. Free resolutions play an important role in commutative algebra, algebraic geometry, and many other neighboring fields. This talk will be an introduction to free resolutions: how to construct them, some key results about them, and some open questions.
