Möbius Polynomials of Face Posets of Convex Polytopes
Meena Jagadeesan, Susan Durst
The Möbius polynomial is an invariant of ranked posets, closely related to the Möbius function. In this paper, we study the Möbius polynomial of face posets of convex polytopes. We…

Möbius Polynomials and Splitting Algebras of Direct Products of Posets
Susan Durst
In this paper, we will study the Möbius polynomial, an invariant of ranked posets that arises in the study of splitting algebras. We will present a formula for the Möbius polynomia…

Universal Labeling Algebras as Invariants of Layered Graphs
Susan Durst
In this work we will study the universal labeling algebra A(Gamma), a related algebra B(Gamma), and their behavior as invariants of layered graphs. We will introduce the notion of…
