On some coupled quasi-fixed point theorems
The author discusses existence of fixed points and coupled quasi-fixed points of mixed monotone operators. Some special cases from [\textit{D. Guo} and \textit{V. Lakshmikantham}, Nonlinear problems in abstract cones, San Diego (1988; Zbl 0661.47045)] are also discussed.
