Abstract: This paper establishes some perturbation analysis for the tensor inverse, the tensor Moore-Penrose inverse, and the tensor system based on the t-product. In the settings of structured perturbations, we generalize the Sherman-Morrison-Woodbury (SMW) formula to the t-product tensor scenarios. The SMW formula can be used to perform the sensitivity analysis for a multilinear system of equations.

Key words: Perturbation analysis, Moore-Penrose inverse, tensor inverse, Multilinear system, Sherman-Morrison-Woodbury (SMW) formula
