• Abstract: Solving systems of partial differential equations (PDEs) is a fundamental task in computational science, traditionally addressed by numerical solvers. Recent advancements have introduced neural operators and physics-informed neural networks (PINNs) to tackle PDEs, achieving reduced computational costs at the expense of solution quality and accuracy. Gaussian processes (GPs) have also been applied to linear PDEs, with the advantage of always yielding precise solutions. In this work, we propose Boundary Ehrenpreis-Palamodov Gaussian Processes (B-EPGPs), a novel framework for constructing GP priors that satisfy both general systems of linear PDEs with constant coefficients and linear boundary conditions. We explicitly construct GP priors for representative PDE systems with practical boundary conditions. Formal proofs of correctness are provided and empirical results demonstrating significant accuracy improvements over state-of-the-art neural operator approaches.

  Partial differential equations (PDEs) are widely used to describe relevant phenomena in dynamical systems. In high-dimensional settings, PINNs often suffer from computational problems because they require dense collocation points over the entire computational domain. We present Physics-Informed Boundary Networks (PIBI-Nets) as a data-driven approach for solving PDEs in one dimension less than the original problem space.
