Quasi-variance of the modulus of homotopical classes of curves and Teichmuller’s problem

Results are obtained on the quasiconformal distortion of the modulus of one and several classes of punctiform curves on the plane. The relationship to Teichmuller's problem for a quadruple of points and the homotopic properties of extremal mappings are studied. In particular, the variation...

Резюме:Results are obtained on the quasiconformal distortion of the modulus of one and several classes of punctiform curves on the plane. The relationship to Teichmuller's problem for a quadruple of points and the homotopic properties of extremal mappings are studied. In particular, the variation of the minimum deviations produced in different motions of one labeled point is studied.
