Ehrhart -distributions
Benjamin Braun, Max Hlavacek, Cesar J. Meza +2
Every polynomial with real non-negative coefficients yields a finite probability distribution after normalization. The Ehrhart -polynomial of a lattice polytope is a non-n…
Lattice slices, Ehrhart polynomials, and magic positivity of generalized parking-function polytopes
Charlie Hill, Ambrose Luo, Vu Trinh +1
For , a -parking function is a sequence of positive integers whose nondecreasing rearrangement $β_1'\l…
Generating Trees and Fibonacci Polyominoes
Juan F. Pulido, José L. Ramírez, Andrés R. Vindas-Meléndez
We study a new class of polyominoes, called -Fibonacci polyominoes, defined using -Fibonacci words. We enumerate these polyominoes by applying generating functions to capture…
Generalized snake posets, order polytopes, and lattice-point enumeration
Eon Lee, Andrés R. Vindas-Meléndez, Zhi Wang
Building from the work of von Bell et al.~(2022), we study the Ehrhart theory of order polytopes arising from a special class of distributive lattices, known as generalized snake p…
Polyhedral geometry of refined -Catalan numbers
Matthias Beck, Mitsuki Hanada, Max Hlavacek +3
We study a refinement of the -Catalan numbers introduced by Xin and Zhang (2022, 2023) using tools from polyhedral geometry. These refined -Catalan numbers depend on a ve…
Matching polytopes, Gorensteinness, and the integer decomposition property
Benjamin Eisley, Koji Matsushita, Andrés R. Vindas-Meléndez
The matching polytope of a graph is the convex hull of the indicator vectors of the matchings on . We characterize the graphs whose associated matching polytopes are Gorenst…
