Stability of high-order Scott-Vogelius elements for 2D non-Newtonian incompressible flow
Charles Parker, Endre Süli
We consider the stability of high-order Scott-Vogelius elements for 2D non-Newtonian incompressible flow problems. For elements of degree 4 or higher, we construct a right-inverse…

Stable Liftings of Polynomial Traces on Tetrahedra
Charles Parker, Endre Süli
On the reference tetrahedron , we construct, for each , a right inverse for the trace operator $u \mapsto (u, \partial_{n} u, \ldots, \partial_{n}^k u)|_{\pa…
