* ABSTRACT

He will give a brief introduction to the conventional nuclear
many-body problem from the perspective of the shell model.
He will introduce several techniques (Folded Diagrams, Lee-Suzuki
similarity transformations, Bloch-Horowitz, etc...) that have long been
used by Shell Model theorists to microscopically derive effective
interactions in a truncated Hilbert space, or model space. These
methods share many similarities with modern Renormalization Group
concepts, which underly the powerful Effective Field Theory approach to
low energy systems. These similarities will be discussed, along with a
list of what is missing in the traditional methods. Our motivation is to
better exploit these similarities, with the hope of removing some of the
model dependence and uncontrolled approximations that have plagued
traditional approaches, while maintaining the calculational simplicity of
the conventional methods.
