Query: Differential geometry of the space of orbits of a Coxeter group   Differential-geometric structures on the space of orbits of a finite Coxeter
group, determined by Groth\'endieck residues, are calculated. This gives a
construction of a 2D topological field theory for an arbitrary Coxeter group.
