Relativistic Calculation of Structure Functions b_{1,2}(X) of the   Deuteron
  The structure functions b_{1,2}^D(X) of the deuteron are studied within covariant approach. It is shown that usual nonrelativistic convolution model result in incorrect behavior of this structure functions at small X and violates the exact sum rules. Realistic calculations are carried out with the Bethe-Salpeter amplitude of the deuteron and compared with the nonrelativistic results.
