We have the following indirect implication of form equivalence classes:
Implication | Reference |
---|---|
90 \(\Rightarrow\) 118 |
Horrors of topology without AC: A non-normal orderable space, van Douwen, E.K. 1985, Proc. Amer. Math. Soc. |
Here are the links and statements of the form equivalence classes referenced above:
Howard-Rubin Number | Statement |
---|---|
90: | \(LW\): Every linearly ordered set can be well ordered. Jech [1973b], p 133. |
118: | Every linearly orderable topological space is normal. Birkhoff [1967], p 241. |
