Planar graphs without normally adjacent short cycles

Fangyao Lu, Mengjiao Rao, Qianqian Wang +1

Let $G$ be the class of plane graphs without triangles normally adjacent to $8^{-}$ -cycles, without $4$ -cycles normally adjacent to $6^{-}$ -cycles, and without normally a…

Cover and variable degeneracy

Fangyao Lu, Qianqian Wang, Tao Wang

Let $f$ be a nonnegative integer valued function on the vertex set of a graph. A graph is \textbf{strictly $f$ -degenerate} if each nonempty subgraph $Γ$ has a vertex $v$ such that…

On the bifurcation set of unique expansions

Charlene Kalle, Derong Kong, Wenxia Li +1

Given a positive integer $M$ , for $q \in (1, M + 1]$ let $U_{q}$ be the set of $x \in [0, M / (q - 1)]$ having a unique $q$ -expansion with the digit set ${0, 1, \dots, M}$ , and l…

Typical points of univoque sets

Derong Kong, Fan Lü

Given a positive integer $M$ and a real number $q > 1$ , we consider the univoque set $U_{q}$ of reals which have a unique $q$ -expansion over the alphabet ${0, 1, \dots, M}$ …
