published as Class.Quant.Grav.25:103001,2008 · 54 pages, 2 figures, invited review paper partially based on various lecture courses, accepted in Classical and Quantum Gravity as topical review. A few changes compared to the original version: some relevant comments on black hole case and references added, typos corrected
We present brief, to great extent pedagogical review on renormalization in curved space-time and of some recent results on the derivation and better understanding of quantum corrections to the action of gravity. The paper is mainly devoted to the semiclassical approach, but we also discuss its importance for quantum gravity and string theory.
