Davenport Constants of Finite Abelian Groups
Dongchun Han, Hanbin Zhang
A central problem in zero-sum theory is to determine the Davenport constant of a finite abelian group. For a finite abelian group , with $…
On zero-sum polytopes: reciprocity, rigidity, and cyclic sieving
Dongchun Han, Xuan Wang, Hanbin Zhang +1
Let be a finite abelian group of order , and let denote the set of zero-sum sequences over of length . We introduce the zero-sum polytope $\mathcal P…
On immanants of Cayley tables
Xuan Wang, Hanbin Zhang
Let be a finite abelian group of order and let be the Cayley table of . Let be the immanant of $\mathcal…
New constructions of NMDS self-dual codes
Dongchun Han, Hanbin Zhang
Near maximum distance separable (NMDS) codes are important in finite geometry and coding theory. Self-dual codes are closely related to combinatorics, lattice theory, and have impo…
On cleanness of von Neumann algebras
Lu Cui, Linzhe Huang, Wenming Wu +2
A unital ring is called clean (resp. strongly clean) if every element can be written as the sum of an invertible element and an idempotent (resp. an invertible element and an idemp…
Erdős-Ginzburg-Ziv theorem and Noether number for
Dongchun Han, Hanbin Zhang
Let be a multiplicative finite group and a sequence over . We call a product-one sequence if holds for some permuta…
