Abstract: | From J-action point of views, slant surfaces are the simplest and the most natural surfaces of a (Lorentzian) Kähler surface (\(\tilde M,\tilde g\), J). Slant surfaces arise naturally and play some important roles in the studies of surfaces of Kähler surfaces (see, for instance, 13]). In this article, we classify quasi-minimal slant surfaces in the Lorentzian complex plane C 1 2 . More precisely, we prove that there exist five large families of quasi-minimal proper slant surfaces in C 1 2 . Conversely, quasi-minimal slant surfaces in C 1 2 are either Lagrangian or locally obtained from one of the five families. Moreover, we prove that quasi-minimal slant surfaces in a non-flat Lorentzian complex space form are Lagrangian. |
