摘要：The purpose of this article is to present a short review of local conformal symmetry in curved
4d space-time. Furthermore we discuss the conformal anomaly and anomaly-induced effective
actions. Despite the conformal symmetry is always broken at quantum level, it may be a basis of
useful and interesting approximations for investigating quantum corrections.
