I started research of mappings between endofuncoids and topological spaces.
Currently the draft is located in volume 2 draft of my online book.
I define mappings back and forth between endofuncoids and topologies.
The main result is a representation of an endofuncoid induced by a topological space.
The formula is .
However I proved this theorem only for the special case if every singleton is a closed set. Also the proof is not yet checked for errors.
