On the Renormalization in Conformal Quantum Gravity
Ioseph L. Buchbinder, Petr M. Lavrov, Thomas M. Sangy +1
One-loop divergences in classically conformal theory in curved spacetime is a nontrivial issue if the theory under consideration possesses gauge invariance. In this case, quantizat…

Renormalizable quantum field theory in curved spacetime with external two-form field
Ioseph L. Buchbinder, Thomas M. Sangy, Ilya L. Shapiro
We argue that the renormalizability of interacting quantum field theory on the curved-space background with an additional external antisymmetric tensor (two-form) field requires no…

On the total derivative divergence for a nonminimal vector operator
Thomas M. Sangy, Tibério de Paula Netto, Ilya L. Shapiro
We report on the calculation of the total derivative term in the divergence of vacuum effective action for the nonminimal vector field operator in a curved space backgroun…
