On Dittmar's approach to the Beltrami equation
Colloquium Mathematicum 92 (2002), 189-195 MSC: 30C62, 35J15. DOI: 10.4064/cm92-2-4
We recall an old result of B. Dittmar. This result permits us to obtain an existence theorem for the Beltrami equation and some other results as a direct consequence of Moser's classical estimates for elliptic operators.
