Query: Quantum gravitational corrections to the stress-energy tensor around the
  rotating BTZ black hole   Modes emerging out of a collapsing black hole are red-shifted to such an
extent that Hawking radiation at future null infinity consists of modes that
have energies beyond the Planck scale at past null infinity. This indicates
that physics at the Planck scale may modify the spectrum of Hawking radiation
and the associated stress-energy tensor of the quantum field. Recently, it has
been shown that, the T-duality symmetry of string fluctuations along compact
extra dimensions leads to a modification of the standard propagator of point
particles in quantum field theory. At low energies (when compared to the string
scale), the modified propagator is found to behave as though the spacetime
possesses a minimal length, say, $\lp$, which we shall assume to be of the
order of the Planck length. We utilize the duality approach to evaluate the
modified propagator around the rotating Banados-Teitelboim-Zanelli black hole
and show that the propagator is finite in the coincident limit. We compute the
stress-energy tensor associated with the modified Green's function and
illustrate graphically that the quantum gravitational corrections turn out to
be negligibly small. We conclude by briefly commenting on the results we have
obtained.
