Title
Max-norm estimates for Stokes and Navier–Stokes approximations in convex polyhedra
Abstract
We prove error estimates in the maximum norm, namely in $$W^{1,\\infty }(\\Omega )^3\\times L^\\infty (\\Omega )$$W1,¿(Ω)3×L¿(Ω), for the Stokes and Navier---Stokes equations in convex, three-dimensional domains $$\\Omega $$Ω with simplicial boundaries. We modify the weighted $$L^2$$L2 estimates for regularized Green functions used earlier by us, which impose restrictions on the domain beyond convexity. The new ingredient is a Hölder regularity estimate proved recently by V. Maz'ya and J. Rossmann for the Stokes system on polyhedra. We also extend the error analysis to $$W^{1,r}(\\Omega )^3\\times L^r(\\Omega )$$W1,r(Ω)3×Lr(Ω) for $$1
