Title: Symmetry and Dynamics of Quantum Field Theories
on Noncommutative Spaces

Abstract: the underlying symmetries of noncommutative
field theories together with their implications are
analyzed. In particular, the concept of a noncommutative
field based on the interplay between twisted Poincare
symmetry and residual symmetry of the Lorentz group
is formulated. Various general dynamical arguments
supporting this construction, such as the light-wedge
causality condition and the integrability condition for
Tomonaga-Schwinger equation, are presented. The use of
the twist procedure for the formulation of noncommutative
gauge field theories is critically considered. Some
problems still to be solved are proposed.
