A combinatorial description of the centralizer algebras connected to the Links-Gould Invariant. (arXiv:1712.04878v1 [math.QA])
来源于:arXiv
In this paper we study the tensor powers of a $4$-dimensional representation
of the quantum super-algebra $U_q(sl(2|1)$, focusing on the rings of its
algebra endomorphisms so called centralizer algebras, denoted by $LG_n$. Their
dimensions were conjectured by I. Marin and E. Wagner \cite{MW}. We will prove
this conjecture, describing the intertwiners spaces from a semi-simple
decomposition as sets consisting in certain paths in a planar lattice with
integer coordinates. 查看全文>>
