Abstract
It is shown that the approximate continuity of the dilatation matrix of a quasiregular mapping f at x implies the local injectivity and the asymptotic linearity of f at x. Sufficient conditions for log|f(x) - f(x)| to behave asymptotically as log|x - x| are given. Some global injectivity results are derived.
