康威甜甜圈

Conway's doughnuts

Peter Doyle, Shikhin Sethi

摘要:

关于角三等分的莫利定理可以被看作是一个特定图形“存在”的陈述,这意味着规定形状的三角形以规定的模式相遇。这个图是n=3的一类图,我们称之为“康威甜甜圈”。这些图可以用John Smillie的holonomy方法证明存在,最近由Eric Braude倡导:“猜测形状;检查holonomy。对于n = 2,3,4,甜甜圈的存在恰好很容易证明,因为洞不存在或三角形。

英文摘要:

Morley's Theorem about angle trisectors can be viewed as the statement that a certain diagram `exists', meaning that triangles of prescribed shapes meet in a prescribed pattern. This diagram is the case n=3 of a class of diagrams we call `Conway's doughnuts'. These diagrams can be proven to exist using John Smillie's holonomy method, recently championed by Eric Braude: `Guess the shapes; check the holonomy.' For n = 2, 3, 4 the existence of the doughnut happens to be easy to prove because the hole is absent or triangular.
