报告摘要：In this talk, we discuss the singular value decomposition of a commutative quaternion tensor under some product. As applications, we give the expression of the Moore-Penrose inverse of a commutative quaternion tensor as well as some properties. Finally，we investigate the general solutions to some commutative quaternion tensor equations when they are consistent and the least-square solutions.
