Para-differential operators in spaces of Triebel-Lizorkin and Besov type
We study the regularity of solutions of nonlinear partial differential equations. J. M. Bony introduced the concept of para-product and the method of para-differential operators in order to prove some theorems about nonlinear partial differential equations. Here we extend results of J. M. Bony and Y. Meyer to Besov and Triebel-Lizorkin spaces. We refer also to new papers by \textit{M. Yamazaki} [J. Fac. Sci., Univ. Tokyo, Sect. I A, 33, 131-174 (1986)].
