  In ``Global existence and scattering for the nonlinear Schrodinger equation
on Schwarzschild manifolds'' (math-ph/0002030), ``Semilinear wave equations on
the Schwarzschild manifold I: Local Decay Estimates'' (gr-qc/0310091), and
``The wave equation on the Schwarzschild metric II: Local Decay for the spin 2
Regge Wheeler equation'' (gr-qc/0310066), local decay estimates were proven for
the (decoupled) Schrodinger, wave, and Regge-Wheeler equations on the
Schwarzschild manifold, using commutator methods. Here, we correct a step in
the commutator argument. The corrected argument works either for radial
semilinear equations or general linear equations. This recovers the results in
math-ph/0002030 and gr-qc/0310066, but does not recover the non radial, large
data, semilinear result asserted in the gr-qc/0310091.
