The covariant technique for the calculation of the heat kernel asymptotic expansion

Abstract We develop a manifestly covariant technique for the calculation of the coefficients of the heat kernel asymptotic expansion in the presence of arbitrary background fields in curved space. The fourth coefficient is explicitly computed.
