Trace anomaly for a conformal 2D vector field model
Samuel W. P. Oliveira, Ilya L. Shapiro
The trace anomaly and anomaly-induced action are evaluated for the two-dimensional vector theory with classical conformal symmetry. Implementing local conformal symmetry while…

Six-dimensional cosmological models with conformal extensions
Daniel Muller, Sergey G. Rubin, Ilya L. Shapiro +1
We consider the background cosmological solutions in the (six-dimensional) model with one time and five space coordinates. The theory of our interest has the action composed b…

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…
