Abstract

For let , i.e. the symmetric part of the polar decomposition of . We consider the relation between two quasiregular mappings whose symmetric part of gradient are close. Our main result is the following. Suppose are -quasiregular mappings with for some and . There exists constant such that if then

Taking we obtain a special case of the quantitative rigidity result of Friesecke, James and Müller [13]. Our main result can be considered as a first step in a new line of generalization of Theorem 1 of [13] in which is replaced by a mapping of non-trivial degree.
