Query: Gravitational vacuum polarization II: Energy conditions in the Boulware
  vacuum   I show that in the Boulware vacuum (1) all standard (point-wise and averaged)
energy conditions are violated throughout the exterior region---all the way
from spatial infinity down to the event horizon, and (2) outside the event
horizon the standard point-wise energy conditions are violated in a maximal
manner: they are violated at all points and for all null/timelike vectors. (The
region inside the event horizon is considerably messier, and of dubious
physical relevance. Nevertheless the standard point-wise energy conditions also
seem to be violated even inside the event horizon.) This is rather different
from the case of the Hartle--Hawking vacuum, wherein violations of the energy
conditions were confined to the region inside the unstable photon orbit. These
calculations are for the quantum stress-energy tensor corresponding to a
conformally-coupled massless scalar field in the Boulware vacuum. I work in the
test-field limit, restrict attention to the Schwarzschild geometry, and invoke
a mixture of analytical and numerical techniques. This *suggests* that general
self-consistent solutions of semiclassical quantum gravity might *not* satisfy
the energy conditions, and may in fact for certain quantum fields and certain
quantum states violate *all* the energy conditions.
