      abstract     = {We study the effect of electron-electron interaction on the
                      one-particle density of states (DOS) rho((d))(epsilon,T) of
                      low-dimensional disordered metals near Fermi energy within
                      the framework of the finite temperature conventional
                      impurity diagram technique. We consider only diffusive limit
                      and, by a geometric resummation of the most singular
                      first-order self-energy corrections via the Dyson equation,
                      we obtain a nondivergent solution for the DOS at low
                      energies while for higher energies the well-known
                      Altshuler-Aronov corrections are recovered. At the Fermi
                      level rho((d))(epsilon,T=0)-> 0, this indicates that
                      interacting disordered two-dimensional and
                      quasi-one-dimensional systems are in insulating state at
                      zero temperature. The obtained results are in good agreement
                      with recent tunneling experiments on two-dimensional
                      GaAs/AlGaAs heterostructures and quasi-one-dimensional doped
                      multiwall carbon nanotubes.},
