The main purpose of this book is to give a detailed and complete survey
of recent progress related to the real-variable theory of
Musielak-Orlicz Hardy-type function spaces, and to lay the foundations
for further applications.
The real-variable theory of function spaces has always been at the core
of harmonic analysis. Recently, motivated by certain questions in
analysis, some more general Musielak-Orlicz Hardy-type function spaces
were introduced. These spaces are defined via growth functions which may
vary in both the spatial variable and the growth variable. By selecting
special growth functions, the resulting spaces may have subtler and
finer structures, which are necessary in order to solve various endpoint
or sharp problems.
This book is written for graduate students and researchers interested
in function spaces and, in particular, Hardy-type spaces.
