A Preliminary Report on Scarf Complexes of Posets

Abstract

The Scarf complex for lattices is well understood and utilized. In 2014, the author expanded the use of the term Scarf complex to encompass an infinite set in $\mathbb{Z}^n$ that was generated via an action of a lattice $\Lambda\in\mathbb{Z}^n$ upon a finite subset $A\subset\mathbb{N}^n$. This paper aims to further generalize the use of Scarf complex by removing the integer lattice completely while maintaining the essence of the Scarf complex.
