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.
