Comment.Math.Univ.Carolinae 38,1 (1997) 121-124.

Abstract:In this paper, we establish a theorem on M\"obius inversion over power set lattices which strongly generalizes an early result of Whitney on graph colouring.

Keywords: M\"obius inversion, power set lattices, graphs, hypergraphs, colourings
