Query: Quantization of the Bianchi type-IX model in supergravity with a
  cosmological constant   Diagonal Bianchi type-IX models are studied in the quantum theory of $ N = 1
$ supergravity with a cosmological constant. It is shown, by imposing the
supersymmetry and Lorentz quantum constraints, that there are no physical
quantum states in this model. The $ k = + 1 $ Friedmann model in supergravity
with cosmological constant does admit quantum states. However, the Bianchi
type-IX model provides a better guide to the behaviour of a generic state,
since more gravitino modes are available to be excited. These results indicate
that there may be no physical quantum states in the full theory of $ N = 1 $
supergravity with a non-zero cosmological constant. are available to be
excited. These results indicate that there may be no physical quantum states in
the full theory of $ N = 1 $ supergravity with a non-zero cosmological
constant.
