Sal?mov %J Ukrainian Mathematical Journal %T Estimation of dilatations for mappings more general than quasiregular mappings %X We consider the so-called ring Q-mappings, which are natural generalizations of quasiregular mappings in a sense of V?ais?al?a?s geometric definition of moduli. It is shown that, under the condition of nondegeneracy of these mappings, their inner dilatation is majorized by a function Q.x/ to within a constant depending solely on the dimension of the space. %N 11 %P 1775-1782 %V 62 %D 2011 %I Springer US %L zu213846
