The main results are by Anderson that are l~2 is homeomorphic to R~∞, and T×Q is homeomorphic to Q ,where Q is the Hilbert cube ,T is the subspase ([0,1]×{0})×({1/2}×[0,1]) of [0,1]×[0,1], which looks like the letterl~2 and R~∞are not homeomorphism ,but it is true for the infinite-dimensional space R~∞? Frech arised the question that whether l.
以l~2为具体的研究对象，重点介绍了Anderson的一些相关工作，例如，l~2同胚于R~∞，T×Q同胚于Q，这里Q表示Hilbert立方，T记为[0，1]×[0，1]的子空间([0，1]×{0})∪({1/2}×[0，1])，这个集合的形状类似于英文字母中的’T’。
