$LD_\gamma ^{p}$ on sets of finite perimeter
Given an open set with finite perimeter 
$\Omega \subset {\open R}^n$, we consider the space 
$LD_\gamma ^{p}(\Omega )$, 
$1\les p<\infty $, of functions with pth-integrable deformation tensor on Ω and with pth-integrable trace value on the essential boundary of Ω. We establish the continuous embedding 
$LD_\gamma ^{p}(\Omega )\subset L^{pN/(N-1)}(\Omega )$. The space 
$LD_\gamma ^{p}(\Omega )$ and this embedding arise naturally in studying the motion of rigid bodies in a viscous, incompressible fluid.
