报告摘要：This talk studies a lateral Cauchy problem for the vibration thin plate equation with incomplete and noisy boundary data. We establish uniqueness in a classical solution class and show that the lateral continuation is intrinsically unstable. To address the resulting numerical instability, we develop a space—time RBF—Kansa approximate-null-space Tikhonov method. For a fixed discretization and a positive regularization parameter, we prove existence and uniqueness of the reduced solution, derive a coefficient-perturbation estimate, and control the PDE collocation residual. Numerical experiments on regular and irregular domains demonstrate the influence of observation geometry, discretization, and data noise, and show improved accuracy over a controlled full-space formulation.
