Abstract
The method of determining the coefficient in the asymptotic expansion of the heat kernel of the Laplacian operator in a Riemann-Cartan space is discussed. In the context of SO(4) gravity with totally antisymmetric torsion tensor, the method of coincidence limits of De Witt (1965) is equivalent to that of the algorithm of 't Hooft (1974). As an example, the axial current divergence due to the spin-1/2 field is given.Keywords
