**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.

**AMS**

This book provides an account of the triangulated theory of motives. Its purpose is to introduce Motivic Cohomology, to develop its main properties, and finally to relate it to other known invariants of algebraic varieties and rings.

**Prerequisites in Algebraic Topology**

by

**Bjorn Ian Dundas**-

**NTNU**

This is not an introductory textbook in algebraic topology, these notes attempt to give an overview of the parts of algebraic topology, and in particular homotopy theory, which are needed in order to appreciate that side of motivic homotopy theory.
