Query: Twisted N=1, d=4 supergravity and its symmetries   We display the construction of a twisted superalgebra for the N=1 Euclidian
supergravity on 4-manifolds with an almost complex structure. It acts on a
representation of twisted supersymmetry made of forms with odd and even
statistics and it is covariant under a SU(2)\subset SO(4) Lorentz invariance of
the manifold's tangent-space. It contains 4 twisted supersymmetry generators,
one nilpotent scalar, one vector and one pseudo-scalar. The superalgebra closes
on the twisted fields of supergravity in its new minimal set of auxiliary
fields. Its couplings to the twisted Wess and Zumino and vector multiplets are
also determined.
