Abstract

It is shown that i) the bilinear/constant and linear/constant “box” elements are not uniformly stable and ii) certain element pairs derived from those above by restricting the pressure spaces are stable. The notion of (div)-semistability is developed to study the behavior of the bilinear/constant and linear/constant “box” elements in detail.
