Twisted Coefficients on coarse Spaces and their Corona

Abstract

To a metric space XX we associate a compact topological space νX\nu' X called the corona of XX. Then a coarse map f:XYf:X\to Y between metric spaces is mapped to a continuous map νf:νXνY\nu' f:\nu' X\to \nu' Y between coronas. Sheaf cohomology on coarse spaces has been introduced in arXiv:1710.06725. We show the functor ν\nu' preserves and reflects sheaf cohomology.
