GLOBAL CONSTANCY PRINCIPLE FOR MIZOHATA OPERATORS
Abstract
In [1] L. Nirenberg constructed a famous example of a smooth vector field which have only the constant functions as solutions in an open subset of the plane. Explanations of this phenomenon have been proposed in Treves [3] and Sjostrand [2]. The explanation in [3] is related to the following so-called "local constancy principle".ple".uot;.
