*Christian Ausoni; Kathryn Hess; Jérôme Scherer*

This volume contains the proceedings of the
Third Arolla Conference on Algebraic Topology, which took place in
Arolla, Switzerland, on August 18–24, 2008.

This volume includes research papers on stable homotopy theory, the
theory of operads, localization and algebraic K-theory, as well as
survey papers on the Witten genus, on localization techniques and on
string topology—offering a broad perspective of modern algebraic
topology.

#### Readership

Graduate students and research mathematicians interested in various aspects of modern algebraic topology.
