Abstract
Numerical calculations based on Kirchhoff laws are used to calculate the resistance of a random mixture of conductors and superconductors on the Sierpinski gasket in two dimensions. Using modified finite-size scaling arguments the authors obtain for the superconductivity exponent s=0.27+or-0.03, which is not predicted by any known critical exponent relations. Their method is confirmed by re-obtaining the exact known result for the conductivity exponent mu for the problem of a conductor-insulator mixture on the gasket.
