Abstract: We introduce a complex purity density and its associated current for pure states of continuous variable systems. The scheme is constructed by analogy with the notions of probability density and probability current. Taking advantage of the formal continuity equations obtained this way we can introduce an entanglement subdynamics. We suggest the use of the dimensionality of this subdynamics as a potential measure of the complexity of entanglement. The scheme also provides insights into the relation between the global and local aspects of quantum correlations.
