摘要
对于保持两个或多个距离的映射f:X→Y来说,其关于推广的Aleksandrov问题的几种情况在本文中被解决.这里的X和Y都是指实内积空间,并且X的维数大于一.
Several cases about the general Aleksandrov problem are resolved for some mapping f.. X→Y preserving two or more distances, where let X and Y be two real inner product spaces with the dimension of X greater than one.
