Local decay rates of best-approximation errors using vector-valued finite elements for fields with low regularity and integrable curl or divergence
We estimate best-approximation errors using vector-valued finite elements for fields with low regularity in the scale of the fractional-order Sobolev spaces. By assuming that the target field enjoys an additional integrability property on its curl or its divergence, we establish upper bounds on thes...
