For algebraic approach toward language, analytic space is prepared
Polydisk Dn that is useful* to identification of some different figures is defined by the following.
Dn = { ( x1, …, xn ) ∈ For all i, xi < 1 }
2
Dn has real topology that is stronger than Zariski topology.
On real topology, refer to the next.
