Schwartz-Zippel bounds for two-dimensional products [PDF]
Schwartz-Zippel bounds for two-dimensional products, Discrete Analysis 2017:20, A famous open problem in combinatorial geometry is Erdős's unit-distances problem, which asks the following: given a subset $A\subset\mathbb R^2$ of size $n$, how many ...

Combinatorial Nullstellensatz modulo prime powers and the Parity Argument [PDF]
We present new generalizations of Olson's theorem and of a consequence of Alon's Combinatorial Nullstellensatz. These enable us to extend some of their combinatorial applications with conditions modulo primes to conditions modulo prime powers. We analyze

Application of the Combinatorial Nullstellensatz to Integer-magic Graph Labelings
Let $A$ be a nontrivial abelian group and $A^* = A \setminus \{0\}$. A graph is $A$-magic if there exists an edge labeling $f$ using elements of $A^*$ which induces a constant vertex labeling of the graph.

Neighbor Sum Distinguishing Total Choosability of IC-Planar Graphs without Theta Graphs Θ2,1,2
A theta graph Θ2,1,2 is a graph obtained by joining two vertices by three internally disjoint paths of lengths 2, 1, and 2. A neighbor sum distinguishing (NSD) total coloring ϕ of G is a proper total coloring of G such that ∑z∈EG(u)∪{u}ϕ(z)≠∑z∈EG(v)∪{v}ϕ(

Graph choosability and double list colorability [PDF]
In this paper, we give a sufficient condition for graph choosability, based on Combinatorial Nullstellensatz and a specific property, called "double list colorability", which means that there is a list assignment for which there are exactly two ...

List circular backbone colouring [PDF]
A natural generalization of graph colouring involves taking colours from a metric space and insisting that the endpoints of an edge receive colours separated by a minimum distance dictated by properties of the edge.

Neighbor Product Distinguishing Total Colorings of Planar Graphs with Maximum Degree at least Ten
A proper [k]-total coloring c of a graph G is a proper total coloring c of G using colors of the set [k] = {1, 2, . . . , k}. Let p(u) denote the product of the color on a vertex u and colors on all the edges incident with u.

Tropical Combinatorial Nullstellensatz and Sparse Polynomials [PDF]
Tropical algebra emerges in many fields of mathematics such as algebraic geometry, mathematical physics and combinatorial optimization. In part, its importance is related to the fact that it makes various parameters of mathematical objects computationally accessible.
