Abstract: In a family of normed conformal mappings defined on the unit disk D and with values in D, which do not admit certain values, we find out an increase of the derivative module at 0 and of the second order term of extended mean value theorem of Taylor. |
Keywords and phrases: conformal mappings, modules of doubly-connected domains, symmetrization.
