Some results on pseudorigid motions
Abstract
Ehlers' and Rudolph's generalization of Born rigidity is analyzed and some properties of the corresponding flow field are derived. We investigate if at the center of motion pseudorigidity reduces to Born rigidity and give some weak criteria for determining if a given motion is pseudo rigid.
