Abstract: Based on both the fundamental theorem of affine geometry in regular L0- modules and the recent progress in random convex analysis, this paper characterizes the stable and fully order preserving and order reversing operators acting on the class of proper lower semicontinuous L0-convex functions in complete random normed modules.
