The Möbius Function of Generalized Factor Order

Robert Willenbring

We use discrete Morse theory to determine the Möbius function of generalized factor order. Ordinary factor order on the Kleene closure A* of a set A is the partial order defined by…

Discrete Morse theory and the consecutive pattern poset

Bruce Sagan, Robert Willenbring

We use discrete Morse theory to provide another proof of Bernini, Ferrari, and Steingrimson's formula for the Mobius function of the consecutive pattern poset. In addition, we are…
