虚Temperley-Lieb代数中的投影

Projectors in the Virtual Temperley-Lieb Algebra

Qingying Deng, Xian'an Jin, Louis H. Kauffman

摘要:

给出了虚Temperley-Lieb代数中投影子的定义方法,推广了Temperley-Lieb代数中的Jones-Wenzl投影子.我们证明了投影机具有与Jones-Wenzl投影机相似的性质,并且包含一个与虚生成元有关的额外性质,即投影机与虚生成元的乘积不变.我们还证明了投影$f_n$在虚Temperley-Lieba代数$VTL_n(d)$中的公理性质的唯一性。最后,我们找到了$f_n$的系数,并给出了投影器$f_n$的显式公式。

英文摘要:

We present a method of defining projectors in the virtual Temperley-Lieb algebra, that generalizes the Jones-Wenzl projectors in Temperley-Lieb algebra. We show that the projectors have similar properties with the Jones-Wenzl projectors, and contain an extra property which is associated with the virtual generator elements, that is, the product of a projector with a virtual generator is unchanged. We also show the uniqueness of the projector $f_n$ in terms of its axiomatic properties in the virtual Temperley-Lieba algebra $VTL_n(d)$. Finally, we find the coefficients of $f_n$ and give an explicit formula for the projector $f_n$.
