arXiv:2607.07006
Abstract
This paper focuses on the analysis of the tensor equation , formulated via the semi tensor product with t-product. For the unknown vector , we establish a necessary and sufficient condition that provides an equivalence criterion for the existence of solutions. For matrix valued and higher-order tensor valued unknown , solvability is determined by corresponding compatibility requirements. Moreover, the explicit structure (Toeplitz and Circulant) of is characterized. The derived results are supported by several illustrative examples.
