Abstract
The functional integral representation for the generating functional of the t-J-V model is obtained. In the case close to half-filling this functional integral representation reduces the conventional Hamiltonian of the t-J-V model to the Hamiltonian of the system containing holes and spins 1/2 at each lattice size. This effective Hamiltonian coincides with that obtained by one of the authors by a different method. This Hamiltonian and its dynamical variables can be used for a description of different magnetic phases of the t-J-V model.
