The vacuum expectation value of energy momentum tensor is one of the important topics to investigate the quantum effect in curved spacetime. Anomaly-induced action, which gives the stress tensor with the same trace as the trace anomaly are expected to be used for compute the VEV of energy momentum tensor mentioned above.
However, in the original formalism, the correspondence between solutions from anomaly-induced action and the related vacuum state is missing. We showed that after introducing the boundary contribution, the correspondence become clearer. For simplicity, our work is in two dimension so far, and we apply this extended formalism to several famous spacetime.
