PINNs error estimates for nonlinear equations in $\mathbb{R}$-smooth Banach spacesJiexing Gao, Yurii Zakharian
In the paper, we describe in operator form classes of PDEs that admit PINN's error estimation. Also, for $L^p$ spaces, we obtain a Bramble-Hilbert type lemma that is a tool for PINN's residuals bounding.
