摘要 运用Liapunov-Schmidt约化和对称破缺分歧的方法,计算了正方形区域上Chan-drasekhar方程边值问题的D4对称的正解. Using the Liapunov - Schmidt reduction and the symmetry-breaking bifurcation theories, we compute and visualize the D4 -symmetric positive solutions of the boundary value problem of the Chandrasekhar equation on the unit square of the plane.
