Query: Mixed Morrey spaces and their applications to partial differential
  equations   In this paper, new classes of functions are defined. These spaces generalize
Morrey spaces and give a refinement of Lebesgue spaces. Some embeddings between
these new classes are also proved. Finally, the authors apply these classes of
functions to obtain regularity results for solutions of partial differential
equations of parabolic type.
