Defective DP-colorings of sparse multigraphs

Yifan Jing, Alexandr Kostochka, Fuhong Ma +2

DP-coloring (also known as correspondence coloring) is a generalization of list coloring developed recently by Dvorak and Postle. We introduce and study $(i, j)$ -defective DP-colori…

Semialgebraic methods and generalized sum-product phenomena

Yifan Jing, Souktik Roy, Chieu-Minh Tran

For a bivariate $P (x, y) \in R [x, y] ∖ (R [x] \cup R [y])$ , our first result shows that for all finite $A \subseteq R$ , $|P(A,A)|\geq α|A|^{5…

Expanding Polynomials and Pairs of Polynomials in Characteristic 0

Yifan Jing, Souktik Roy, Chieu-Minh Tran

We begin a generalized study of sum-product type phenomenon in different fields by considering pairs $P (x, y)$ and $Q (x, y)$ of two variable polynomials that simultaneously exhibit s…

Small doublings in abelian groups of prime power torsion

Yifan Jing, Souktik Roy

Let $A$ be a subset of $G$ , where $G$ is a finite abelian group of torsion $r$ . It was conjectured by Ruzsa that if $∣ A + A ∣ \leq K ∣ A ∣$ , then $A$ is contained in a coset of $G$ of siz…

Non-bipartite distance-regular graphs with a small smallest eigenvalue

Zhi Qiao, Yifan Jing, Jack Koolen

In 2017, Qiao and Koolen showed that for any fixed integer $D \geq 3$ , there are only finitely many such graphs with $θ_{m i n} \leq - α k$ , where $0 < α < 1$ is any fixed number. In this p…
