“…These include the ENO schemes of Osher, Sethian, and Shu [30,31] and the WENO schemes of Jiang and Peng [16]. Similar methods on triangular meshes include the pioneering works of Abgrall [1,2], Augoula and Abgrall [3], Barth and Sethian [5], Kossioris, Makridakis, and Souganidis [19], and the recent work of Zhang and Shu [35] on WENO schemes for HJ equations on triangular meshes. The high-order WENO reconstructions on triangular meshes that were used in [35] were based on the results of Hu and Shu [15].…”
