Query: Remark on the global non-existence of semirelativistic equations with
  non-gauge invariant power type nonlinearity with mass   The non-existence of global solutions for semirelativistic equations with
non-gauge invariant power type nonlinearity with mass is studied in the frame
work of weighted $L^1$. In particular, a priori control of weighted integral of
solutions is obtained by introducing a pointwise estimate of fractional
derivative of some weight functions. Especially, small data blowup with small
mass is obtained.
