Dilaton gravity in two-dimensions

摘要: Abstract The study of general two-dimensional models gravity allows to tackle basic questions quantum gravity, bypassing important technical complications which make the treatment in higher dimensions difficult. As physically examples spherically symmetric Black Holes, together with string inspired models, belong this class, valuable knowledge can also be gained for these systems case. In last decade, new insights regarding exact quantization geometric part such theories have been obtained. They allow a systematic field theoretical treatment, interactions matter, without explicit introduction specific classical background geometry. present review tries assemble results coherent manner, putting them at same time into perspective quite large literature on subject.
