Query: Noncommutative fields and actions of twisted Poincare algebra   Within the context of the twisted Poincar\'e algebra, there exists no
noncommutative analogue of the Minkowski space interpreted as the homogeneous
space of the Poincar\'e group quotiented by the Lorentz group. The usual
definition of commutative classical fields as sections of associated vector
bundles on the homogeneous space does not generalise to the noncommutative
setting, and the twisted Poincar\'e algebra does not act on noncommutative
fields in a canonical way. We make a tentative proposal for the definition of
noncommutative classical fields of any spin over the Moyal space, which has the
desired representation theoretical properties. We also suggest a way to search
for noncommutative Minkowski spaces suitable for studying noncommutative field
theory with deformed Poincar\'e symmetries.
