Title: Path-Integral Fujikawa's Approach to Anomalous Virial Theorems

Abstract: We derive anomalous equations of state for non-relativistic 2D complex 
bosonic elds 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) Schrodinger 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 
calculation of the Jacobian will be mentioned at the end of the seminar.
