Seminário "Anomaly-induced effective action of gravity and stability of classical solutions"

“Our goal in this work is to derive the equation for gravitational waves in gravity theory with anomaly-induced quantum corrections on the general homogeneous and isotropic background. After this we verify the stability of such background with respect to metric perturbations. This problem has several interesting applications. One is to explore the stability of the classical cosmological solutions in the theory with quantum effects. For this, we analyze the behaviour of metric perturbations during inflationary period, in the stable phase of the Modified Starobinsky inflation.”
