Complete Computation of DeWitt-Seeley-Gilkey Coefficient E4 for Nonminimal Operator on Curved Manifolds
نویسندگان
چکیده
Asymptotic heat kernel expansion for nonminimal differential operators on curved manifolds in the presence of gauge fields is considered. The complete expressions for the fourth coefficient (E4) in the heat kernel expansion for such operators are presented for the first time. The expressions were computed for general case of manifolds of arbitrary dimension n and also for the most important case n = 4. The calculations have been carried out on PC with the help of a program written in C.

متن کاملHeat Invariant E2 for Nonminimal Operator on Manifolds with Torsion
Computer algebra methods are applied to investigation of spectral asymptotics of elliptic differential operators on curved manifolds with torsion and in the presence of a gauge field. In this paper we present complete expressions for the second coefficient (E2) in the heat kernel expansion for nonminimal operator on manifolds with nonzero torsion. The expressions were computed for general case ...
متن کاملHeat Kernel Expansion for Operators of the Type of the Square Root of the Laplace Operator
A method is suggested for the calculation of the DeWitt-Seeley-Gilkey (DWSG) coefficients for the operator √ −∇2 + V (x) basing on a generalization of the pseudodifferential operator technique. The lowest DWSG coefficients for the operator √ −∇2 + V (x) are calculated by using the method proposed. It is shown that the method admits a generalization to the case of operators of the type (−∇2 + V ...
متن کاملComputer Algebra Study of Spectral Invariants of Differential Operators on Curved Manifolds
We consider asymptotic heat kernel expansion for elliptic differential operators acting on compact closed curved manifolds. The coefficients in this expansion are quantities of fundamental importance in quantum field theory, quantum gravity, spectral geometry and topology of manifolds. Obtaining explicit expressions for these quantities is very laborious task, especially in the problems of mode...
متن کاملProof of the symmetry of the off - diagonal Hadamard / Seeley - deWitt ’ s coefficients in C ∞ Lorentzian mani - folds by a “ local Wick rotation ”
Abstract: Completing the results achieved in a previous paper, we prove the symmetry of Hadamard/Seeley-deWitt off-diagonal coefficients in smooth D-dimensional Lorentzian manifolds. To this end, it is shown that, in any Lorentzian manifold, a sort of “local Wick rotation” of the metric can be performed provided the metric is a locally analytic function of the coordinates and the coordinates ar...
