Propose une méthode pour détecter des petits clusters du "côté droit" du graphe (les noeuds $j \in V$). Avec des tailles de clusters de l'ordre de $n_{2}^{\varepsilon}$ où $\varepsilon>0$ La preuve de la proposition 4 sur la récupération des clusters de $V$ est intéressante. %% end user_notes %% # Annotations importées %% begin annotations %% ## Importées : 2026-05-22 3:23 pm Quote > For V there are clusters V1, … , Vk with Vi ⊆ V ; we do not assume that the Vj are disjoint or that their union equals V Quote > Fix two probabilities p > q ≥ 0.
