Abstract
The truncated eigenvalue equation is derived from the improved U(1) lattice gauge field Hamiltonian. The vacuum wave function in 2 + 1 dimensional U(1 ) model is computed. The numerical results conform our expectation that the scaling behavior of the vacuum wave function can be greatly improved by, i mproving the lattice Hamiltonian.
