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.

Title: "The Structure of the Nucleon"

Abstract:
"In this colloquium talk I will present general ideas and basic concepts of how the substructure of the nucleon can be accessed both from the theoretical side and from the experimental side. A substructure of nucleons implies that nucleons are composite particles that consist of more elementary particles, the so-called partons. The modern theory of the strong nuclear force, Quantum Chromodynamics (QCD), identifies these partons as quarks and gluons. Within QCD the structure of the nucleon in terms of quarks and gluons is encoded in so-called parton distribution functions. In my talk I will discuss various types of parton distribution functions and how they can be extracted from experimental data. Of particular interest are parton distribution functions that depend on the transverse momentum of quarks and gluons in a fast moving nucleon as they provide a 3-dimesional picture of the nucleon structure."
