We consider the heat kernel for a massless fermion of spin 1/2 interacting with all types of non-Abelian boson fields, i.e. scalar, pseudo-scalar, vector, axial-vector and antisymmetric tensor fields, in a four-dimensional Riemannian space. The coupl

We evaluate two covariant gravitational anomalies, i.e. Einstein and Lorentz anomalies, on chiral gauge theories in four-dimensional curved space with torsion, so-called Riemann-Cartan space. It is shown that the `pure' Einstein anomaly Gν and the `

We clarify the dependence on the torsion tensor of all coefficients in the covariant Taylor expansion of the HMDS coefficient in the heat kernel for the fermion of spin in Riemann-Cartan space. The dependence on the torsion tensor of the quantities i

The chiral U (1) anomaly in d=4, N=1 supergravity is evaluated on the basis of the heat kernel method. We consider all gravitino interactions of the theory, i.e. not only the minimal coupling of gravitino and gravitational fields, but also four-gravi

We analytically derive transition probabilities for four-neutrino oscillations in matter. The time evolution operator giving the neutrino oscillations is expressed by the finite sum of terms up to the third power of the Hamiltonian in a matrix form,
