摘要：

We study geometry of two-dimensional models of conformal space-time based on the group of Mobius transformation. The natural geometric invariants, called cycles, are used to linearize Mobius action. Conformal completion of the space-time is achieved through an addition of a zero-radius cycle at infinity. We pay an attention to the natural condition of nonreversibility of time arrow in order to get a correct compactification in the hyperbolic case.
