In this set of lecture notes the author includes some of the latest research on the theory of
Morrey Spaces associated with Harmonic Analysis. There are three main claims concerning these
spaces that are covered: determining the integrability classes of the trace of Riesz potentials
of an arbitrary Morrey function determining the dimensions of singular sets of weak solutions
of PDE (e.g. The Meyers-Elcart System) and determining whether there are any full
interpolation results for linear operators between Morrey spaces. This book will serve as a
useful reference to graduate students and researchers interested in Potential Theory Harmonic
Analysis PDE and or Morrey Space Theory.
