Lưu Trích dẫn Chia sẻAbstract
In this paper, we consider the nonlinear biharmonic equation. The problem is ill‐posed in the sense of Hadamard. To obtain a stable numerical solution, we consider a regularization method. We show rigourously, with error estimates provided, that the corresponding regularized solutions converge to the true solution strongly in urn:x-wiley:mma:media:mma5771:mma5771-math-0001 uniformly with respect to the space coordinate under some a priori assumptions on the solution.
