On the structure of the topological phase of two-dimensional gravity

摘要: Abstract The topological phase of two-dimensional gravity is re-examined. correlation functions the naturally occuring operators in minimal model are computed, using methods, genus zero and one. genus-zero results agree with recent obtained exact solutions “matrix models”, suggesting that two approaches to equivalent. coupling sigma models investigated. CP1 appears be almost as simple pure theory. General, model-independent properties which hold arbitrary field theories can serve a qualitative definition gravity. A number facts familiar usual string theory, such relation between vanishing canonical line bundle Kahler manifold scale invariance corresponding have simpler echoes phase.
