One-particle irreducibility of Vilkovisky-DeWitt effective action
Sukanta Panda, Abbas Tinwala, Ketankumar Jadav
The effective action formalism introduced by Vilkovisky and later modified by DeWitt is completely covariant suitable for obtaining an effective action that is independent of the p…

Two-loop Vilkovisky-DeWitt effective action for scalar field minimally coupled with gravity
Ketankumar Jadav, Sukanta Panda, Abbas Altafhussain Tinwala
It is known that Vilkovisky-DeWitt's effective action is gauge invariant off-shell and independent of quantum field parametrization. In this work, we perform the calculation of the…
