In mathematics, pointless topology (also called point-free or pointfree topology) is an approach to topology that avoids mentioning points.
Description
The name 'pointless topology' is due to John von Neumann.
The ideas of pointless topology are closely related to mereotopologies in which regions (sets) are treated as foundational without explicit reference to underlying point sets.
