Recently, verified computation has emerged as a powerful tool for providing explicit error estimates for numerical solutions to boundary value and eigenvalue problems of differential operators. The author’s recent book [1] surveys these developments, showcasing significant progress in the field. In this talk, I will summarize the latest results on verified computation, with a focus on spectral problems and solution verification for the Navier-Stokes equations [2].
Additionally, I will outline the objectives of an ongoing project aimed at verifying the existence of multiple solutions to the Navier-Stokes equations in 3D domains. This discussion will highlight several key challenges associated with this goal.
