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.

When a category has some notion of limits and colimits associated to it, its ordinary limits and colimits are not necessarily homotopically meaningful. We ...

In this chapter, we generalize homotopy limits and colimits from cubical to arbitrary diagrams of spaces. It should be clear by now that the motivation for ...
