Abstract
Numerical simulations of diffusion processes are performed on fractal aggregates designed to mimic the structure of inhomogeneous granular superconductors. The spectral dimensions obtained yield ftuctuation-conductivity exponents that are compared with experimental results on ceramic samples ofhigh-Tc oxides ofthe YBaCuO system.
