Title: 
On the Master Constraint Operator for Loop
Quantum Gravity 
Abstract: 
A Master Constraint Operator $\hat{\mathbf{M}}$ can be
densely defined in the diffeomorphism invariant
Hilbert space in loop quantum gravity. The
corresponding quadratic form coincides with the one
proposed by Thiemann in the master constraint
programme. It is shown that $\hat{\mathbf{M}}$ is
positive and symmetric, and hence has its Friedrichs
selfadjoint extension. So the master constraint
programme for loop quantum gravity can be carried out
in principle by employing $\hat{\mathbf{M}}$.
