Hölder Continuity of the Data to Solution Map for HR in the Weak Topology

Abstract

It is shown that the data to solution map for the hyperelastic rod equation is Hölder continuous from bounded sets of Sobolev spaces with exponent $s>3/2$ measured in a weaker Sobolev norm with index $r<s$ in both the periodic and non-periodic cases. The proof is based on energy estimates coupled with a delicate commutator estimate and multiplier estimate.
