Extremal persistence probabilities of exchangeable sign-invariant random variables

Daniel Iľkovič, Jun Yan

Let $(X_{1}, \dots, X_{n})$ be a random variable in $(R ∖ {0})^{n}$ that is both exchangeable and sign-invariant. For every $k \in [n]$ , let $S_{k} = \sum_{i = 1}^{k} X_{i}$ . Define t…

Exact enumeration of lozenge tilings of a triangular region

Jun Yan

We prove that the number of lozenge tilings of a certain triangular region $T_{n}$ is given by the formula \[T_n=\prod_{\substack{1\leq a<b\leq 3n+2\\(a,b)\not=(n+1,2n+2)}}…
