*Path-Integral Fujikawa's Approach to Anomalous Virial Theorems *

We derive anomalous equations of state for non-relativistic 2D complex 
bosonic fields with contact interactions, using
Fujikawa's path-integral approach to anomalies and scaling arguments. In 
the process, we derive an anomalous virial
theorem for such systems. The methods used are easily generalizable for 
other 2D systems, including fermionic ones,
and of different spatial dimensionality, all of which share a classical 
SO(2,1) Schrödinger symmetry. The discussion is of
a more formal nature and is intended mainly to shed light on the 
structure of anomalies in 2D many-body systems. The
practicality of these ideas rests upon being able to compute in detail 
the Fujikawa Jacobian that contains the anomaly.
This and other technical and conceptual issues and some recent results 
on the calculaltion of the Jacobian will be
mentioned at the end of the seminar.
