Effective action and Schwinger-DeWitt technique in DGP brane models
A. O. Barvinsky, D. V. Nesterov
We give blueprints of the Schwinger-DeWitt technique for the covariant curvature expansion of quantum effective action for the DGP type models in curved spacetime.
Effective action and heat kernel in a toy model of brane-induced gravity
A. O. Barvinsky, A. Yu. Kamenshchik, C. Kiefer +1
We apply a recently suggested technique of the Neumann-Dirichlet reduction to a toy model of brane-induced gravity for the calculation of its quantum one-loop effective action. Thi…
Nonperturbative heat kernel and nonlocal effective action
A. O. Barvinsky, D. V. Nesterov
We present an overview of recent nonperturbative results in the theory of heat kernel and its late time asymptotics responsible for the infrared behavior of quantum effective actio…
Duality of the Dirichlet and Neumann problems in braneworld physics
D. V. Nesterov, A. O. Barvinsky
Braneworld effective action for two-brane model is constructed by two different methods based respectively on the Dirichlet and Neumann boundary value problems. The equivalence of…
Quantum Cauchy problem in cosmology
A. O. Barvinsky, D. V. Nesterov
We develop a general framework for effective equations of expectation values in quantum cosmology and pose for them the quantum Cauchy problem with no-boundary and tunneling wavefu…
