Homotopy invariance of convolution products
Steffen Sagave, Stefan Schwede
The purpose of this paper is to show that various convolution products are fully homotopical, meaning that they preserve weak equivalences in both variables without any cofibrancy…

Categories and orbispaces
Stefan Schwede
Constructing and manipulating homotopy types from categorical input data has been an important theme in algebraic topology for decades. Every category gives rise to a `classifying…

Global homotopy theory
Stefan Schwede
This book introduces a new context for global homotopy theory, i.e., equivariant homotopy theory with universal symmetries. Many important equivariant theories naturally exist not…
