  With the Cowling approximation, the torsional oscillations on relativistic
stars in tensor-vector-scalar (TeVeS) theory are examined. The spectrum
features in TeVeS are very similar to those in general relativity (GR), but the
torsional frequencies in TeVeS become larger than those expected in GR. We find
that, compared with the fluid oscillations with polar parity, the torsional
frequencies depend strongly on the gravitational theory. Since the dependences
of fundamental frequencies on the gravitational theory and on the equation of
state are different from those of overtone, it could be possible to distinguish
TeVeS from GR in the strong-field regime via observations of this type of
oscillations with the help of the observation of stellar mass.
