Hölder estimates and hypoellipticity
Annales de l'Institut Fourier, Tome 26 (1976) no. 2, pp. 35-54

The aim of this paper is to show how, in order to prove regularity theorems, Hölder estimates, i.e. estimates involving products of powers of different semi-norms, can be used as well as standard estimates, and may in some instances be casier to prove.

Cet article a pour but de montrer comment, en vue de prouver certains théorèmes de régularité, des estimations classiques peuvent être remplacées par des estimations höldériennes, c’est-à-dire faisant intervenir des produits de puissances de différentes semi-normes ; ces dernières peuvent parfois être plus faciles à établir.
