摘要
We prove a spectral multiplier theorem for non-self-adjoint operators. More precisely, we consider non-self-adjoint operators A : D(A) subset of L(2) -> L(2) having numerical range in a sector Sigma(w) of angle w, and whose heat kernel satisfies a Gaussian upper bound. We prove that for every bounded holomorphic function f on Sigma(w), f(A) acts on L(p) with L(p)-norm estimated by the behavior of a finite number of derivatives of f on the boundary of Sigma(w).
