Reworking the Antonsen-Bormann idea
The Antonsen - Bormann idea was originally proposed by these authors for the computation of the heat kernel in curved space; it was also used by the author recently with the same objective but for the Lagrangian density for a real massive scalar field in 2 + 1 dimensional curved space. It is now reworked here with a different purpose - namely, to determine the zeta function for the said model using the Schwinger operator expansion.
