A hamiltonian formulation of Yang-Mills theories in the pure temporal gauge

A canonical hamiltonian quantization of Yang-Mills theories is developed in the pure time-like axial gauge, obtaining for the gluons (photons) a prescription similar to the one originally proposed by Mandelstam and Leibbrandt for the light-like case. In a redundant Hilbert space a physical subspace with positive-semidefinite inner product is defined, where the Gauss law and Poincare covariance are recovered and the perturbative scattering matrix is unitary.
