Abstract

Let M₁³(c) be an 3-dimensional Lorentz space form and C(M₁³(c)) denote the conformal transformation group of M₁³(c). A spacelike surface x:M²→M₁³(c) is called a conformal homogeneous spacelike surface. If there exists a subgroup G⊂C(M₁³(c)) such that the orbit G(p)=x(M²),p∈x(M²). In this paper, we classify completely conformal homogeneous spacelike surfaces up to a conformal transformation of M₁³(c).
