Abstract
We manifest the origin of the wrong conclusion made by several groups of au thors on the absence of Coulomb corrections to the cross section of the e()e(-) pair production in ultrarelativistic heavy-ion collisions. The source of the mistake is connected with an incorrect passage to the limit in the expression for the cross section. When this error is eliminated, the Coulom b corrections do not vanish, and agree with the results obtained within the Weizsacker-Williams approximation.
