三元q-Virasoro-Witt Hom-Nambu-李代数

Ternary q-Virasoro-Witt Hom-Nambu-Lie algebras

F. Ammar, A. Makhlouf, S. Silvestrov

摘要:

本文利用$su(1,1)$包络代数技术构造了三值$q$ -Virasoro-Witt代数,并将Curville,Fairlie和Zachos构造的三值Virasoro-Witt代数进行了$q$ -变形. Curville,Fairlie和Zachos构造的三值Virasoro-Witt代数依赖于一个参数,并且对于这个参数的所有值都不是Nambu-李代数.对于使三值Virasoro-Witt代数为Nambu-Lie的参数值,本文构造的相应的三值$q$ -Virasoro-Witt代数也是Hom-Nambu-Lie,因为它们是由三值Nambu-李代数用合成方法得到的.对于其它参数值,该复合方法不能给出$q$ -Virasoro-Witt代数的Hom-Nambu李代数结构.然而,我们表明,使用不同的建设,即三进制Virasoro-维特代数的Cursley,费尔利和Zachos,以及一般的三进制$q$ -Virasoro-维特代数,我们建设,进行结构的三进制Hom-Nambu-李代数的所有值所涉及的参数。

英文摘要:

In this paper we construct ternary $q$-Virasoro-Witt algebras which $q$-deform the ternary Virasoro-Witt algebras constructed by Curtright, Fairlie and Zachos using $su(1,1)$ enveloping algebra techniques. The ternary Virasoro-Witt algebras constructed by Curtright, Fairlie and Zachos depend on a parameter and are not Nambu-Lie algebras for all but finitely many values of this parameter. For the parameter values for which the ternary Virasoro-Witt algebras are Nambu-Lie, the corresponding ternary $q$-Virasoro-Witt algebras constructed in this article are also Hom-Nambu-Lie because they are obtained from the ternary Nambu-Lie algebras using the composition method. For other parameter values this composition method does not yield Hom-Nambu Lie algebra structure for $q$-Virasoro-Witt algebras. We show however, using a different construction, that the ternary Virasoro-Witt algebras of Curtright, Fairlie and Zachos, as well as the general ternary $q$-Virasoro-Witt algebras we construct, carry a structure of ternary Hom-Nambu-Lie algebra for all values of the involved parameters.
