The purpose of this paper is to give a selective survey on recent progress in random metric theory and its applications to conditional risk measures. This paper includes eight sections. Section 1 is a longer introduction, which gives a brief introduction to random metric theory, risk measures and conditional risk measures. Section 2 gives the central framework in random metric theory, topological structures, important examples, the notions of a random conjugate space and the Hahn-Banach theorems for random linear functionals. Section 3 gives several important representation theorems for random conjugate spaces. Section 4 gives characterizations for a complete random normed module to be random reflexive. Section 5 gives hyperplane separation theorems currently available in random locally convex modules. Section 6 gives the theory of random duality with respect to the locallyL0-convex topology and in particular a characterization for a locallyL0-convex module to beL0-pre-barreled. Section 7 gives some basic results onL0-convex analysis together with some applications to conditional risk measures. Finally, Section 8 is devoted to extensions of conditional convex risk measures, which shows that every representableL∞-type of conditional convex risk measure and every continuousLp-type of convex conditional risk measure (1 ≤p< +∞) can be extended to an-type ofσε,λ-lower semicontinuous conditional convex risk measure and an-type of-continuous conditional convex risk measure (1 ≤p< +∞), respectively.
