摘要

It is shown that the Kronecker product can be applied to constructing new discrete integrable coupling system of soliton equation hierarchy in this paper.A direct application to the fractional cubic Volterra lattice spectral problem leads to a novel integrable coupling system of soliton equation hierarchy.It is also indicated that the study of discrete integrable couplings by using the Kronecker product is an efficient and straightforward method.This method can be used generally.
