On a homeomorphism between the Sorgenfrey line S and its modification Sp
A topological space S P , which is a modification of the Sorgenfrey line S, is considered. It is defined as follows: if x ∈ P ⊂ S, then a base of neighborhoods of x is the family {[x, x + ε), ε > 0} of half-open intervals, and if x ∈ SP, then a base of neighborhoods of x is the family {(x − ε, x]...
