Erdős also contributed to fields in which he had little real interest, such as topology, where he is credited as the first person to give an example of a totally disconnected topological space that is not zero-dimensional, the Erdős space.
Erdős tamén contribuíu en campos nos que tiña pouco interese como a topoloxía, dando o primeiro exemplo de espazo totalmente inconexo que non é cero-dimensional.
