Abstract.

It is known that the curvature measures of parallel ɛ-neighbourhoods of a set with positive reach or a polyconvex set converge vaguely if ɛ tends to zero to the curvature measures of the set itself. We show that in the case of a set with positive reach, the total variations of the curvature measures converge as well, whereas in the case of a polyconvex set this is no more true in general.
