Classification of quasi-minimal slant surfaces in Lorentzian complex space forms. (English) Zbl 1199.53167
The authors classify quasi-minimal slant surfaces in the Lorentzian complex plane. There exist five large families of quasi-minimal proper slant surfaces in C21. Quasi-minimal slant surfaces in C21 are either Lagrangian or locally obtained from one of the five families. Quasi-minimal slant surfaces in a non-flat Lorentzian complex space form are Lagrangian.
