Abstract
The truncated eigenvalue equation of SU(N) lattice gauge theory is studied by using improved lattice gauge Hamiltonian with a proper truncation scheme that preserves the continuum limit. The calculations of vacuum state wavef unction and glueball mass of (2+1)-dimensional SU(2) theory up to third ord er sere carried out, the results show the improvement of scaling behavior i n deep weak coupling region.
