TY - JOUR TI - A fractal variational theory of the Broer-Kaup system in shallow water waves AU - Ling Wei-Wei AU - Wu Pin-Xia JN - Thermal Science PY - 2021 VL - 25 IS - 3 SP - 2051 EP - 2056 PT - Article AB - The Broer-Kaup equation is one of many equations describing some phenomena of shallow water wave. There are many errors in scientific research because of the existence of the non-smooth boundaries. In this paper, we generalize the Broer-Kaup equation to the fractal space and establish fractal variational formulations through the semi-inverse method. The acquired fractal variational formulation reveals conservation laws in an energy form in the fractal space and suggests possible solution structures of the morphology of the solitary waves DO - 10.2298/TSCI180510087L ER -
