The paper “Multi-symplectic simulations of W/M-shape-peaks solitons and cuspons for FORQ equation“, co-authored by Weipeng Hu (Xi’an University), Zhengqi Han (Xi’an University), Tom Bridges, and Zhijun Qiao (University of Texas Rio Grande), has been published in Applied Mathematics Letters (link here). In the paper, the multisymplectic structure for FORQ is derived and used as a basis for constructing a multi-symplectic discretization. The screenshot below shows the multi-symplectic structure of FORQ.
