Summary.
-
This paper contains theorems which describe the correspondence
between topological properties of real numbers subsets introduced
in [35] and introduced in [33],
[14]. We also show the homeomorphism
between the cartesian product of two $R^1$ and ${\cal E}^2_{\rm T}$.
The compactness of the bounded closed subset of
${\cal E}^2_{\rm T}$ is proven.
