Error estimates for some quasi-interpolation operators

We derive explicit bounds on the constants in error estimates for two quasi-interpolation operators which are modifications of the “classical” Clement-operator. These estimates are crucial for making explicit the constants which appear in popular a posteriori error estimates. They are also compared with corresponding estimates for the standard nodal interpolation operator.
