loc solution to the
Beltrami equation @f = ? @f is the so-called ring Q\{homeomorphism with
Q(z) = K?(z) where K?(z) is the dilatation quotient of this equation. On
this base, it is stated equicontinuity and normality of families of such solu-
tions under the conditions that K?(z) has a majorant of ?nite mean oscil-
lRation, singularities of logarithmic type or integral constraints of the type

function ? are not only su?cient but also necessary for equicontinuity and
normality of the corresponding families of solutions to the Beltrami equa-
