At small distances (large momenta) the resulting propagator passes on to the standard (nonperturbative) gluon propagator used in the perturbative quantum chromodynamics (QCD). The results suggest some scenario of linear confinement for mesons and quarkonia which is also outlined. As a consequence there arises a motivation for studying the relativistic bound states in the above confining SU($N$)-Yang-Mills fields. This possiblity is realized for $N=2,3,4$ with the aid of the black hole theory results about spinor fields on black holes with a subsequent application to the charmonium spectrum in the most important physical case N=3. Incidentally uniqueness of the confining solutions is discussed and a comparison with the nonrelativistic potential approach is given.
