The Separating Noether Number of Finite Abelian Groups

Jing Huang

For a finite abelian group $G$ , let $I^_{sep}^{2} (G)$ denote its separating Noether number. We determine $I^_{sep}^{2} (G)$ exactly for every finite abelian group $ G \con…

A Proof of a Conjecture of MÃ³ricz and Nagy on Rational-Value Sums

Jing Huang

MÃ³ricz and Nagy introduced the problem of maximizing the number of $r$ -element subsets with rational sums in an $n$ -element set of irrational numbers, and showed that it is equiva…

Sharp lower bounds and extremal graphs for the generalized $k$ -independence number

Jing Huang, Jiaxin Tang

A vertex set $S$ is a generalized $k$ -independent set if the induced subgraph $G [S]$ contains no tree on $k$ vertices. The generalized $k$ -independence number $I^\pm_{k} (G)$ is the maxi…

A sharp lower bound on the generalized 4-independence number

Jing Huang

For a graph $G$ , a vertex subset $S$ is called a maximum generalized $k$ -independent set if the induced subgraph $G [S]$ does not contain a $k$ -tree as its subgraph, and the subset…
