Jones-Wenzl投影公式

A Formula for the Jones-Wenzl Projections

Scott Morrison

摘要:

本文提出了一种计算Temperley-Lieb代数中Jones-Wenzl投影系数的方法。它基本上重复了Frenkel和Khovanov在1997年发表的方法。我在2002年中期写了这封信,当时我并不知道他们的工作,但在发现他们的文章后,我把它放在了一边。最近,我决定把它掸掉灰尘,放在arXiv上--希望我在这里给出的独立而详细的证明可能有用。它也被引用了很多次,所以我想最好给它一个永久的家。证明是基于一个简化的Wenzl递归关系。文中给出了一个算例,并将此方法与Ocneanu提出并由Reznikoff部分证明的公式进行了比较。我还描述了一些图表上的动作,这些动作以一种简单的方式修改了它们的系数。

英文摘要:

I present a method of calculating the coefficients appearing in the Jones-Wenzl projections in the Temperley-Lieb algebras. It essentially repeats the approach of Frenkel and Khovanov published in 1997. I wrote this note mid-2002, not knowing about their work, but then set it aside upon discovering their article. Recently I decided to dust it off and place it on the arXiv --- hoping the self-contained and detailed proof I give here may be useful. It's also been cited a number of times, so I thought it best to give it a permanent home. The proof is based upon a simplification of the Wenzl recurrence relation. I give an example calculation, and compare this method to the formula announced by Ocneanu and partially proved by Reznikoff. I also describe certain moves on diagrams which modify their coefficients in a simple way.
