The minimal angle condition for quadrilateral finite elements of arbitrary degree

Acosta Gabriel, Monzon Gabriel

We study $W^{1, p}$ Lagrange interpolation error estimates for general quadrilateral $Q_{k}$ finite elements with $k \geq 2$ . For the most standard case of $p = 2$ it turns ou…

Error estimates for Raviart-Thomas interpolation of any order on anisotropic tetrahedra

G. Acosta, Th. Apel, R. G. Durán +1

We prove optimal order error estimates for the Raviart-Thomas interpolation of arbitrary order under the maximum angle condition for triangles and under two generalizations of this…
