【摘要】：利用降階法給出二維擴(kuò)展Fisher-Kolmogorov方程的三層線性化緊差分格式,證明了解的存在唯一性及在L∞范數(shù)下時(shí)間方向二階收斂、空間方向四階收斂.最后通過(guò)數(shù)值算例,驗(yàn)證差分格式是有效的.
[Abstract]:By using the reduced order method, the three-layer linearized compact difference scheme for two-dimensional extended Fisher-Kolmogorov equation is given. The existence and uniqueness of the solution and the second order convergence in the time direction and the fourth order convergence in the space direction under L 鈭，
