While studying inhomogeneous, degenerate Beltrami equations, the
following question arises in a natural way: what are the weights
\omega such that any Beltrami diferential operator dominates the full
differential in the L^p(\omega) norm? In the Cauchy-Riemann setting,
we know that the answer is given by the class of Muckenhoupt weights.
Unfortunately, for a general Beltrami operators the situation might be
different. We will give some partial answers. We will also comment on
some connections with quasiconformality, and finally we will pose some
open problems.
