Abstract
Given a measurable function with
, the approximating solutions of Beltrami equation for
are directly constructed by using the techniques of SG circle pattern and conformal welding. It is proved that the sequence of approximating solutions converges uniformly on to compact subsets to a quasiconformal mapping with complex dilation
. This provides a new approach of constructing discrete quasiconformal mappings.
