Relativistic Effects in the Electromagnetic Structure of $\rho$-meson
  The relativistic calculations of the electromagnetic form factors and static moments of $\rho$-meson are given in the framework of the relativistic Hamiltonian dynamics with different model wave functions. The impulse approximation is used. Lorentz covariance and conservation law for the electromagnetic current operator are taken into account.
