Recent neutron-scattering experiments in the superconducting state
of YBa2Cu3O6+x have been interpreted in terms of a magnetic collective
mode whose dispersion relative to the commensurate wave vector has
a curvature opposite in sign to a conventional magnon dispersion.
The purpose of this article is to demonstrate that simple linear-response
calculations are in support of a collective-mode interpretation,
and to explain why the dispersion has the curvature it does.
