### Adaptive Finite element approximation of steady flows of incompressible fluids with implicit power-law-like rheology

Abstract:

We develop the a posteriori error analysis of finite element approximations of implicit power-law-like models for viscous incompressible fluids. The Cauchy stress and the symmetric part of the velocity gradient in the class of models under consideration are related by a, possibly multi--valued, maximal monotone $r$-graph, with $\frac{2d}{d+1} <$r\$ < ∞. We establish upper and lower bounds on the finite element residual, as well as the local stability of the error bound. We then consider...
