Parametrices for a class of P.D. operators and applications
and Hölder estimates for pseudodifferential operators : sufficient conditions
Richard Beals (1979)
Annales de l'institut Fourier
Similarity:
Continuity in spaces and spaces of Hölder type is proved for pseudodifferential operators of order zero, under general conditions on the class of symbols. Applications to the regularity theory of some hypoelliptic operators are outlined.

Similarity:
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.
