ejde-279	Li, Xinyue; Zhang, Yongli; Zhang, Huiqun; Zhao, Qiulan	Lie symmetry analysis and conservation laws for the (2+1)-dimensional Mikhalev equation	2021	14	.pdf	application/pdf	5616	268	76	(3.31) Substituting (3.31) into (1.1), it is easily to obtain the reduced nonlinear PDE with variable coefficients through a straight calculation 2v3fv + v4fvv + c4vfvw − c4wfww − 2v2ffv + wv2ffwv (3.27) 8 X. Y. LI, H. Q. ZHANG, Y. L. ZHANG, Q. L. ZHAO EJDE-2021/41 Solving this equation, we obtain v = (c3 − d3)y − d2x, w = t, u = d4 d2 y + f(w, v).	cache/ejde-279.pdf	txt/ejde-279.txt
