The repulsive screened Coulomb interaction has been found to be a poss
ible channel for the mechanism of electron pairing. This becomes possi
ble only if one takes into account the renormalization of interaction
due to involving the background particles (holes). An perturbative app
roach of the treatment of a many-particle system has been developed by
the authors.(1,2) Critical temperature T-c is given by the pole condi
tion of effective interaction. It is also found that conductivity tend
s to infinity with the transition induced. it seems that superconducti
vity stems from the well-known, but not yet well treated Coulomb inter
action in an anisotropic many-particle system.
