摘要
In this paper, we study the Kuramoto-Sivashinsky (KS) equation backward in time. First, we prove a stability estimate of H & ouml;lder type. Then the ill-posed problem is regularized by the Tikhonov regularization method, and an error estimate of H & ouml;lder type is obtained. Finally, we apply a physics-informed neural network method to solve the problem numerically.
