In [[mathematics]], the '''Lebesgue covering dimension''' or '''topological dimension''' of a [[topological space]] is one of several different ways of defining the [[dimension]] of the space in a
[[topological invariant|topologically invariant]] way.<ref name="Lebesgue">{{cite journal|url=http://matwbn.icm.edu.pl/ksiazki/fm/fm2/fm2130.pdf|title=Sur les correspondances entre les points de deux espaces|volume= 2 |year= 1921|first=Henri|last= Lebesgue| author-link= Henri Lebesgue|journal=
