Local theta correspondences between epipelagic supercuspidal representations

In this paper we study the local theta correspondences between epipelagic supercupsidal representations of a type I classical dual pair $(G,G')$ over $p$-adic fields. We show that, besides an exceptional case, an epipelagic supercupsidal representation $\pi$ of $\widetilde{G}$ lifts to an epipelagic supercupsidal representation $\pi'$ of $\widetilde{G}'$ if and only if the epipelagic data of $\pi$ and $\pi'$ are related by the moment maps.
