  The renormalization problem of (2+1)-dimensional Yang-Mills theory quantized
on the light front is considered. Extra fields analogous to those used in
Pauli-Villars regularization are introduced to restore perturbative equivalence
between such quantized theory and conventional formulation in Lorentz
coordinates. These fields also provide necessary ultraviolet regularization to
the theory. Obtained results allow to construct renormalized Hamiltonian of the
theory on the light front.
