2-距离空间中两个膨胀型映射的公共不动点定理

The Common Fixed Point Theorem for Two Mappings of Expansion in 2-metric Spaces

（X，d）为一完备的2-距离空间，A，B为两个X到X的膨胀型映射，本文的工作是在（X，d）中讨论了A，B的公共不动点问题，得到了一个公共不动点定理。

Let (X,d ) be a complete 2-metric space, A,B are two mappings of expansion from X to X. This paper considers the problems of the common fixed point of A and B in 2 -metric space (X,d ),and obtains a theorem.
