Let T t be the semigroup of linear operators generated by a Schrödinger operator − A = Δ − V , where V is a non‐negative polynomial, and let∫ 0 ∞ λ d E A ( λ )be the spectral resolution of A . We say that f is an element ofH A pif the maximal function M f ( x ) = sup t >0 | T t f ( x )| belongs to L p . We prove a criterion of Mihlin type on functions F which implies boundedness of the operators F ( A ) = ∫ 0 ∞ F ( λ ) d E A ( λ )onH A p , 0 < p ⩽ 1. 1991 Mathematics Subject Classification 42B30, 35J10.
