Quadrilaterals and extremal quasiconformal extensions

J. M. Anderson, A. Hinkkanen

Research output: Contribution to journalArticlepeer-review


We show that the smallest maximal dilatation for a quasiconformal extension of a quasisymmetric function of the unit circle may be larger than indicated by the change in the module of the quadrilaterals with vertices on the circle.
