摘要：

A general method of calibrations is developed for the study of minimal Χ-Lagrangian surfaces in almost-Hermitian manifolds. A criterion for minimality of Χ-Lagrangian surfaces is given, along with a lower bound for the second variation of the volume functional on minimal hi;-Lagrangian surfaces in Hermitian manifolds.The generalized Maslov index of these surfaces is shown to be trivial. © 1990 American Mathematical Society.
