Explicit inverse matrices of Tribonacci skew circulant type matrices

摘要

The determinants and inverses of Tribonacci skew circulant type matrices are discussed in the paper. Firstly, Tribonacci skew circulant type matrices are defined. In addition, we show the invertibility of the Tribonacci skew circulant matrix and present the determinant and the inverse matrix based on constructing the transformation matrices. By utilizing the relation between circulant and left circulant, the invertibility of the Tribonacci skew left circulant are also discussed. Finally, the determinants and the inverse matrices of these matrices are given, respectively.
