\noindent {\bf TITLE}: ``Diffusion Approximation for a Processor Sharing Queue in Heavy Traffic"
 
\noindent {\bf ABSTRACT}: We discuss a diffusion approximation result for the queue
length process of a GI/GI/1 processor sharing queue in heavy traffic.
The main approach is to study a certain measure valued process, which
encodes information about the residual service times and from which
standard measures of performance such as queue length, workload and
sojourn time can be recovered.
