Abstract:
In [1] and [2] the problem of spectral synthesis for a subspace W invariant under a differential operator with constant coefficients was reduced to a check of two properties of its annihilator submodule I=AnW: stability and saturation. The present article describes a situation in which this check leads to a positive result, i.e., the annihilator submodule I is ample.
