摘要:

我们介绍了几十个实验发现的不变量的Poncelet N-π s的共焦椭圆对(椭圆台球)。回想一下,这个族是由两个运动积分(线动量和角动量)完全定义的,所以任何“新”的不变量都依赖于它们。然而,证明它们可能需要复杂的方法。我们参考一些二十几个证明已经贡献。我们希望这篇文章能激励那些仍然缺乏证据的人做出贡献。

英文摘要:

We introduce several-dozen experimentally-found invariants of Poncelet N-periodics in the confocal ellipse pair (Elliptic Billiard). Recall this family is fully defined by two integrals of motion (linear and angular momentum), so any "new" invariants are dependent upon them. Nevertheless, proving them may require sophisticated methods. We reference some two-dozen proofs already contributed. We hope this article will motivate contributions for those still lacking proof.
