Poincar\ue9 constants for finite element stars

We derive sharp and explicit upper bounds for possibly weighted Poincar\ue9 constants of finite element stars. The latter are star-shaped domains that consist of a finite number of nonoverlapping simplices or parallelepipeds which all share a common vertex. Bounds for Poincar\ue9 constants are needed in deriving error estimates for quasi-interpolation operators and a posteriori upper bounds
