Maximal function characterizations for variable Hardy spaces on spaces of homogeneous type

  • Yao He

摘要

Let \((\mathcal {X}, d, \mu )\) ( X , d , μ ) be a metric measure space of homogeneous type with finite measure and let \(p(\cdot ): \mathcal {X} \rightarrow (0,1]\) p ( · ) : X ( 0 , 1 ] be a variable exponent function satisfying the globally log-Hölder continuous condition. In this paper, we obtain non-tangential and radial maximal function characterizations for variable Hardy spaces associated to a non-negative self-adjoint operator satisfying Gaussian estimates on a space of homogeneous type with finite measure.
