  We show the dynamical stability of a six-dimensional braneworld solution with
warped flux compactification recently found by the authors. We consider linear
perturbations around this background spacetime, assuming the axisymmetry in the
extra dimensions. The perturbations are expanded by scalar-, vector- and
tensor-type harmonics of the four-dimensional Minkoswki spacetime and we
analyze each type separately. It is found that there is no unstable mode in
each sector and that there are zero modes only in the tensor sector,
corresponding to the four-dimensional gravitons. We also obtain the first few
Kaluza-Klein modes in each sector.
