Stolz Positive Scalar Curvature Structure Groups, Proper Actions and Equivariant 2-Types

Massimiliano Puglisi, Thomas Schick, Vito Felice Zenobi

In this note, we study equivariant versions of Stolz' $R$-groups, the positive scalar curvature structure groups $R_n^{\mathrm{spin}}(X{)}^G$, for proper actions of discrete groups $G$. W…
