摘要
We study general spectral multiplier theorems for nonnegative self-adjoint operators on spaces of homogeneous type. We show that a Hormander type spectral multiplier theorem follows from sub-Gaussian upper bounds for the corresponding heat kernel. Our result can be applied to fractal manifolds and quantum graphs.
