Spatial quasiregular mappings with distortion close to one
Abstract.
We discuss a quantitative proof for the following result
of
Martio, Rickman and Väisälä: for each dimension n>2,
there exists a
number
K(n)>1, so that all non-constant n-dimensional
K-quasiregular
mappings
with K(n)>k are local homeomorphisms.
