Abstract
We give necessary and sufficient conditions of equicontinuity of so-called ring \(Q\)-mappings that will have significant applications to the general Beltrami equation, a complex form of one of the main equations of the mathematical physics in the plane, as well as to its many-dimensional analogs and to the Orlicz–Sobolev mappings in space.
