Outline of Final Research Achievements |
By the method of random discretization we considered the discrete Laplacian of nets on a compact Riemannian manifold or Alexandorv space. Using the Laplacian we constructed the Hamiltonian ofvibrations on net and its quantum statistical mechanics. By perturbation expansion of its thermodynamical functions we introduced a family of the Riemannian metrics on the bulk moduli space of the pairs of space and net. Then we studied its relation to the Gromov-Hausdorff distance and several classical moduli spaces.
