摘要:

多项式B-样条的扩展定义可能为改进经典三次多项式B-样条所得结果提供机会。通过扫描包含零的某些区间确定扩展参数的最优值。本研究旨在通过扩展的三次B-样条置位法求解构造于Gardner方程的初值边界值问题。测试问题源自某些解析研究以验证所提方法的有效性和准确性。此外,还确定了守恒律以观察其在理论上预期的保持恒定性。通过von Neumann分析研究了所提方法的稳定性。

英文摘要:

The extended definition of the polynomial B-splines may give a chance to improve the results obtained by the classical cubic polynomial B-splines. Determination of the optimum value of the extension parameter can be achieved by scanning some intervals containing zero. This study aims to solve some initial boundary value problems con- structed for the Gardner equation by the extended cubic B-spline collocation method.The test problems are derived from some analytical studies to validate the efficiency and accuracy of the suggested method. The conservation laws are also determined to observe them remain constant as expected in theoretical aspect. The stability of the proposed method is investigated by the Von Neumann analysis.
