For an open set Ω ⊂ R dwe study the algebra M ( Ω ) of continuous linear operators onC ∞ ( Ω )admitting the monomials as eigenvectors. We give a concrete representation of these operators and evaluate it explicitly for the unit ball and the whole of R d . We also study the topology of M ( Ω ) and the algebra of eigenvalue sequences.
