Partitioning bases of topological spaces
Abstract
We investigate whether an arbitrary base for a dense-in-itself topological space can be partitioned into two bases. We prove that every base for a T3 Lindel\"of topology can be partitioned into two bases while there exists a consistent example of a first countable, 0-dimensional, Hausdorff space of size continuum and weight ω1 which admits a point countable base without a partition to two bases. Several related results are proved and the paper finishes with a list of open problems.
