正方形上p-Henon方程多个正解的计算
COMPUTING THE MULTIPLE POSITIVE SOLUTIONS TO p-HENON EQUATION ON A SQUARE
【摘要】 本文首先给出计算正方形上p-Henon方程边值问题D4对称正解的算法,然后以参数r为分歧参数,在D4对称正解解枝上用扩张系统方法求出对称破缺分歧点,进而用解枝转接方法计算出其它具有不同对称性质的正解.
【Abstract】 In this paper,the algorithms are applied to solving the D4 symmetric positive solutions to the boundary value problem of p-Henon equation.Taking r in p-Henon equation as a bifurcation parameter,the symmetry-breaking bifurcation point on the branch of the D4 symmetric positive solutions is found via the extended systems.Finally,other symmetric positive solutions are computed by the branch switching method based on the Liapunov-Schmidt reduction.
