construct two non-homeomorphic topological spaces

57 Views Asked by At

Construct two topological spaces $X,Y$ satisfying that $X$ is not homeomorphic to $Y$, but $X\times[0,1]$ is homeomorphic to $Y\times[0,1]$

i just solve the condition with $[0,1)$. Have no good idea of this construction.

Any idea is helpful. thanks
