Abstract
In this paper, we prove that the dimension of the space of bounded energy-finite solutions for the Schrodinger operator is invariant under rough isometries between complete Riemannian manifolds satisfying the local volume condition, the local Poincare inequality and the local Sobolev inequality. We also prove that the dimension of the space of bounded harmonic functions with finite Dirichlet integral is invariant under rough isometries between complete Riemannian manifolds satisfying the same local conditions. These results generalize those of Kanai, Grigor'yan, the second author, and Li and Tam.
