**A Primer on Homotopy Colimits**

by Daniel Dugger

**Publisher**: University of Oregon 2008**Number of pages**: 72

**Description**:

This is an expository paper on homotopy colimits and homotopy limits. These are constructions which should arguably be in the toolkit of every modern algebraic topologist. Many proofs are avoided, or perhaps just sketched.
