On the $C$ -diversity of intersecting hypergraphs

Peter Frankl, Jian Wang

Let $F \subset (k X)$ be a family consisting of $k$ -subsets of the $n$ -set $X$ . Suppose that $F$ is intersecting, i.e., $F \cap F^{'} \neq = \emptyset$ for all $…

Quantitative stochastic homogenization for random conductance models with stable-like jumps

Xin Chen, Zhen-Qing Chen, Takashi Kumagai +1

We consider random conductance models with long range jumps on $Z^{d}$ , where the one-step transition probability from $x$ to $y$ is proportional to $w_{x, y} ∣ x - y ∣^{- d - α}$ with $α\in…

Improved bounds on the maximum diversity of intersecting families

Peter Frankl, Jian Wang

A family $F \subset (k [ n ])$ is called an intersecting family if $F \cap F^{'} \neq = \emptyset$ for all $F, F^{'} \in F$ . If $\cap F \neq = \emptyset$ then $\…

Minimum degree thresholds for Hamilton $(ℓ, k - ℓ)$ -cycles in $k$ -uniform hypergraphs

Jian Wang, Jie You

Let $n > k > ℓ$ be positive integers. We say a $k$ -uniform hypergraph $H$ contains a Hamilton $(ℓ, k - ℓ)$ -cycle if there is a partition $(L_0,R_0,L_1,R_1,\ldots,L_{t-1…

Extremal Problem for Matchings and Rainbow Matchings on Direct Products

Jian Wang, Jie You

Let $n_{1}, \dots, n_{ℓ}, k_{1}, \dots, k_{ℓ}$ be integers and let $V_{1}, \dots, V_{ℓ}$ be disjoint sets with $∣ V_{i} ∣ = n_{i}$ for $i = 1, \dots, ℓ$ . Define $⊔_{i = 1}^{ℓ} (k _{i} V _{i})$ a…

A question of Norton-Sullivan in the analytic case

Jian Wang, Hui Yang

In 1996, A. Norton and D. Sullivan asked the following question: If $f : T^{2} \to T^{2}$ is a diffeomorphism, $h : T^{2} \to T^{2}$ is a contin…

On bifurcation of eigenvalues along convex symplectic paths

Yinshan Chang, Yiming Long, Jian Wang

We consider a continuously differentiable curve $t \mapsto γ (t)$ in the space of $2 n \times 2 n$ real symplectic matrices, which is the solution of the following ODE: $\frac{\mathrm{d…
