一种新的再生核希尔伯特空间方法被应用于最终超定的二维抛物线逆源问题。精确解和近似解都是在再生核空间中获得的。证明了近似解及其偏导数分别收敛于精确解及其偏导数。提出了一种技术来改进一些现有方法。数值结果表明该方法具有较高的精度,证实了该方法重建源参数的鲁棒性。
A new method of the reproducing kernel Hilbert space is applied to a two-dimensional parabolic inverse source problem with the final overdetermination. The exact and approximate solutions are both obtained in a reproducing kernel space. The approximate solution and its partial derivatives are proved to converge to the exact solution and its partial derivatives, respectively. A technique is proposed to improve some existing methods. Numerical results show that the method is of high precision, and confirm the robustness of our method for reconstructing source parameter.
