Abstract
For surfaces in complex space forms with almost complex structure J, flat surfaces are the simplest ones from intrinsic point of view. From J-action point of view, the most natural surfaces are slant surfaces. The classification of flat slant surfaces in C2 was done in [2]. In this paper we apply a result of [5] to study flat slant surfaces in CP 2 and CH 2. We prove that, for any θ, there exist infinitely many flat θ-slant surfaces in CP 2 and CH 2. And there does not exist flat half-minimal proper slant surface in CP 2 and in CH 2.
