Collar neighbourhoods for topological manifolds.
The well-known collar neighbourhood theorem states:
Let $M$ be a smooth manifold with compact boundary $\partial M$, then there exists a neighbourhood of $\partial M$, which is diffeomorphic to $\partial M\times [0,1)$.
I am asking myself if the theorem holds in the topological category. Is it true at least for compact topological manifolds?
My first idea would be to take a more closer look at the work of Kirby and Siebenmann on topological manifolds, but since I am absolutely not an expert in this field, I hoped to get an answer with a reference or a counterexample here.
This is a special case of the main result of this paper:
Morton Brown, "Locally flat imbeddings of topological manifolds", Annals of Mathematics, Vol. 75 (1962), p. 331-341.
Edit: See also Proposition 3.42 in Hatcher's "Algebraic Topology" for a self-contained proof of the existence of a boundary collar for manifolds with boundary. Hatcher assumes that the manifold is compact but his proof only uses compactness of the boundary.
