Abstract
From the fluctuation conductivity behavior of a system information con cerning its dimensionality and its change with temperature can be stud ied and the cross-over point of this change can be determined as well. Besides the above characteristics sometimes, depending on the relatio ns of some constants of the material, percolative fractal behavior eme rges in the fluctuation behavior. The above behavior has been recogniz ed out of paraconductivity measurements in a polycrystal YBaCuO sample as it has been also observed in some other samples.
