Abstract
Let L be a nonnegative self-adjoint operator on L2(X), where X is a space of homogeneous type. Assume that L generates an analytic semigroup e-tL whose kernel satisfies the standard Gaussian upper bounds. We prove that the spectral multiplier F(L) is bounded on Hp L(X) for 0 < p ≤ 1, the Hardy space associated to operator L, when F is a suitable function.
