Query: Real frequency tearing layers with parallel dynamics and the effect on
  locking and resistive wall modes   Tearing modes with real frequencies in the plasma frame (i.e. in addition to
the Doppler shift due to $E\times B$ rotation) are of potential importance
because of their effect on the locking process. In particular, it has recently
been shown [J. M. Finn, A. J. Cole, and D. P. Brennan, Phys. Plasmas (Letters),
22:120701, 2015] that the Maxwell torque on the plasma in the presence of an
applied error field is modified significantly for tearing modes having real
frequencies near marginal stability. In addition, it is known [J. M. Finn and
R. A. Gerwin, Phys. Plasmas, 3:2344, 1996] that resistive wall tearing modes
can be destabilized below their no-wall limits by rotation, if the tearing
modes have real frequencies near marginal stability. In this paper we first
derive the tearing mode dispersion relation with pressure gradient, field line
curvature and parallel dynamics in the resistive-inertial (RI) regime,
neglecting the divergence of the $E\times B$ drift and perpendicular
resistivity. The results show that the usual Glasser effect, a toroidal effect
which involves real frequencies, occurs in this simplified model, which ignores
perpendicular resistivity and the divergence of the $E\times B$ drift. We also
find, using a similar simple model, the surprising result that in the
viscoresistive regime with pressure gradient, favorable curvature due to
toroidal effects, and parallel dynamics, a similar Glasser-like effect is
found. We show that in both regimes the existence of tearing modes with complex
frequencies is related to nearby electrostatic resistive interchange modes with
complex frequencies. We discuss the effect on locking to an error field and the
significant lowering of the threshold for destabilization of resistive wall
tearing modes, which can be much more pronounced than the weak effect observed
for RI tearing modes without pressure-curvature drive in Finn and Gerwin, 1996.
