The Polyakov loop and the heat kernel expansion at finite temperature
E. Megias, E. Ruiz Arriola, L. L. Salcedo
The lower order terms of the heat kernel expansion at coincident points are computed in the context of finite temperature quantum field theory for flat space-time and in the presen…
Anomalies for Nonlocal Dirac Operators
E. Ruiz Arriola, L. L. Salcedo
The anomalies of a very general class of non local Dirac operators are computed using the -function definition of the fermionic determinant and an asymmetric version of the Wign…
Chiral and scale anomalies of non local Dirac operators
E. Ruiz Arriola, L. L. Salcedo
The chiral and scale anomalies of a very general class of non local Dirac operators are computed using the -function definition of the fermionic determinant. For the axial anoma…
Wigner transformation for the determinant of Dirac operators
L. L. Salcedo, E. Ruiz Arriola
We use the -function regularization and an integral representation of the complex power of a pseudo differential operator, to give an unambiguous definition of the determinant o…
