These notes present an introduction into the spectrum of the category of modules over a ring. We discuss the general theory of pure-injective modules and concen

The last few years have seen a revolution in our understanding of the foundations of stable homotopy theory. Many symmetric monoidal model categories of spectra

This book introduces a new point-set level approach to stable homotopy theory that has already had many applications and promises to have a lasting impact on th

Gives a theory $S$-modules for Morel and Voevodsky's category of algebraic spectra over an arbitrary field $k$. This work also defines universe change functors,

The Handbook of Homotopy Theory provides a panoramic view of an active area in mathematics that is currently seeing dramatic solutions to long-standing open pro
