A classical theorem of H. Hopf asserts that a closed connected smooth
manifold admits a nowhere vanishing vector field if and only if its
Euler characteristic is zero. R Brown generalized Hopf's result
to topological manifolds, replacing vector fields with path fields.
In this note, we give an equivariant analog of Brown's theorem for
locally smooth $G$-manifolds where $G$ is a finite group.
