Explicit density computations for certain sets of primes in Lucas sequences

Joaquim Cera Da Conceicao · 2026

Let $U$ be a Lucas sequence, $p$ be prime, and $\rho_U(p)$ be the rank of appearance of $p$ in $U$. We derive closed-form formulas for the Dirichlet density of primes $p$ for which $d\mid \rho_U(p)$, …

Achieving the Kesten-Stigum bound in the non-uniform hypergraph stochastic block model

Manuel Fernandez V, Ludovic Stephan, Yizhe Zhu · 2026

We study the community detection problem in the non-uniform hypergraph stochastic block model (HSBM), where hyperedges of varying sizes coexist. This setting captures higher-order and multi-view inter…
