Abstract
In this second part of the book, we assume readers are familiar with notions, properties, and notations about the Fourier transform on L 2, Sobolev spaces and inequalities, absolutely continuous functions, and distributions. Readers who are not accustomed to these concepts are therefore invited to consult the very end of this book, where two small chapters are devoted to them. They should also consult [302, 303], and [326] for further reading.
