Rigidity and stability for biased cross-intersecting families

Yongjiang Wu, Lihua Feng

Let $p = (p_{1}, \dots, p_{n})$ and $q = (q_{1}, \dots, q_{n})$ belong to $(0, 1/2]^{n}$ , and let $μ_{p}$ and $μ_{q}$ be the associated measures on $2^{[n]}$ . Suppos…

The binomial norm of intersecting-union families

Yongjiang Wu, Lihua Feng

In a 2021 survey on Katona's circle method, Frankl conjectured that every family $F \subseteq 2^{[n]}$ in which any two members intersect and no two members cover $[n]$ sa…

Random partition for Tokushige's $r$ -wise intersecting conjecture

Yongjiang Wu, Lihua Feng

Let $r \geq 3$ and let $1 > p_{1} \geq p_{2} \geq \dots \geq p_{n} > 0$ . Let $μ_{p}$ denote the product measure on $2^{[n]}$ where each coordinate $i$ is included independently with probabil…

Bollobás-type inequalities for subspaces via weight invariance

Zhiyi Liu, Lihua Feng, Tingzeng Wu

Let $V$ be an $n$ -dimension real vector space with a direct sum decomposition $V = V_{1} \oplus \dots \oplus V_{r}$ . Let $P = {(A_{i}, B_{i}) : i \in [m]}$ be a skew Bollobás…

Subspace variations of the weighted skew Bollobás theorem

Yongjiang Wu, Yongtao Li, Lu Lu +1

Let $V$ be a finite-dimensional real vector space. A collection $P = {(A_{i}, B_{i})}_{i = 1}^{m}$ of pairs of subspaces of $V$ is called a skew Bollobás system if $\dim(A_i\cap…

The number of rooted spanning forests of bicirculant graphs

Jing Yang, Lihua Feng, Rongrong Lu +1

A bi-Cayley graph over the cyclic group $(Z_{n}, +)$ is called a bicirculant graph. Let $Γ = B C (Z_{n}; R, T, S)$ be a bicirculant graph with $R=-R\subseteq \mathbb{Z}_n\s…
