摘要：Given a domain D, f is K-quasiconformal self-map of D with identity boundary values. In this talk, we introduce some recent results on Teichmuller's problem which
is to determine how far a given point x in D can be mapped under f. We estimate this distance between x and f(x) from the above by using two different metrics, the distance ratio metric and the quasihyperbolic metric. We study Teichmuller’s problem for Gromov hyperbolic domains with identity values at the boundary of infinity. As applications, we obtain results on Teichmuller’s problem for quasihyperbolic uniform domains and inner uniform domains.
