Topological characteristics of space \(Q(k)\) and \(Q\times B(k)\)
The author describes a nonseparable analog \(Q(k)\) of the space of rational numbers Q. The internal characteristics of spaces \(Q(k)\) and \(Q\times B(k)\) are given. It is shown that spaces \(Q(\tau)\times B(k)\) and \(Q\times B(k)\) are homeomorphic if \(\omega\leq \tau \leq k\).
