The Cauchy problem for the Hunter-Saxton equation is known to be locally well posed in Besov spaces B-2,r(s) on the circle. We prove that the data-to-solution map is not uniformly continuous from any bounded subset of B(2,)(r)s to C([0, T]; B(2,)(r)s). We also show that the solution map is Holder continuous with respect to a weaker topology.
