Möbius Inversion in Lattices
Henry H. Crapo · Birkhäuser Boston eBooks · 2009
In the development of computational techniques for combinatorial theory, attention has lately centered on R OTA’S theory of Möbius inversion [6]. The main theorem of R OTA’S paper, concerning the computation of the Möbius invariant across a Galois connection, is a prerequisite to the use of lattice-theoretic methods in combinatorics.
