The main results of the present paper are: For any bounded D in space Cn, there is an analytic invariant λ(D)(≤1). If D is a transitive domain, then λ(D)<1 and k0(D)=(λ(D))/(1-λ(D)), where k0(D) is the Schwarz constant of domain D (cf[1]). And we have discussed the Characteristic properties of λ(D). |
