雪球是准球
Snowballs are Quasiballs
摘要：
我们引入雪球，这是紧集$\R^3$同胚的单位球。它们是由雪花曲线界定的平面中的域的三维类似物。对于每个雪球$B$，构造将$B$映射到单位球的拟共形映射$f\colon \R^3\to \R^3$。
英文摘要：
We introduce snowballs, which are compact sets in $\R^3$ homeomorphic to the unit ball. They are 3-dimensional analogs of domains in the plane bounded by snowflake curves. For each snowball $B$ a quasiconformal map $f\colon \R^3\to \R^3$ is constructed that maps $B$ to the unit ball.
