New doubly periodic and multiple soliton solutions of the generalized (3+l)-dimensional KP equation with variable coefficients 下载免费PDF全文
A new generalized Jacobi elliptic function method is used to construct the exact travelling wave solutions of nonlinear partial differential equations (PDEs) in a unified way. The main idea of this method is to take full advantage of the elliptic equation which has more new solutions. More new doubly periodic and multiple soliton solutions are obtained for the generalized (3+1)-dimensional Kronig-Penny (KP) equation with variable coefficients. This method can be applied to other equations with variable coefficients. 相似文献

关于图升分解为独立边集问题 总被引:1,自引:0,他引:1
Alavi[1]给出了图的升分解概念,并猜想每一图都可升分解.本文证明了边数为(?)的图G当边色数X'(G)≤(n+2)/2时可升分解为{Gi}, 1≤i≤n, Gi≈iK2. 相似文献
