Contribution

It introduces a comprehensive approach using anomaly-induced effective actions to study quantum effects on black holes, wormholes, and the initial singularity in cosmology.

Findings

Confirmation of primordial wormhole formation in the early universe

Discussion of anti-evaporation phenomena in multi-horizon black holes

Quantum corrections potentially explain primordial black hole properties

Abstract

We review the anomaly induced effective action for dilaton coupled spinors and scalars in large N and s-wave approximation. It may be applied to study the following fundamental problems: construction of quantum corrected black holes (BHs), inducing of primordial wormholes in the early Universe (this effect is confirmed) and the solution of initial singularity problem. The recently discovered anti-evaporation of multiple horizon BHs is discussed. The existance of such primordial BHs may be interpreted as SUSY manifestation. Quantum corrections to BHs thermodynamics maybe also discussed within such scheme.
