| Abstract: | The boundary correspondence of the affine stretch A K(z)=K x+iy in the hyperbolic regions{z=x+iy:x 2a 2-y 2b 2>1,x>0} is proved to have the property that the extremal maximal dilatation is equal to the supremum of the ratios of the moduli of quadrilaterals. |

| Keywords: | quasisymmetric homeomorphism substantial point modulus of quadrilateral |
