报告摘要：

Given a domainD, f is K-quasiconformal self-map of D with identity boundary values. In this talk, we introduce some reent results om 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() from the above by using two diferent metrics, the ditance ratio metric and the quasithyperbolic metic. We study Teichmuller's problem for Gromow hyperbolic domains with identity values at the boundary of infnity. As applications, we obtain results on Teichmullers problem for quasihyperbolic uniform domains and inner uniform domains.
