In this work, we present and prove the explicit formula for the determinant of a class of nonsymmetric Toeplitz matrices. Setting up one of the nonzero subdiagonals to zero results in special pentadiagonal Toeplitz matrices, whose determinant formulas are conjectured by Anđelić and Fonseca in Anđelić [Some determinantal considerations for pentadiagonal matrices. Linear Multilinear Algebra. 2020. DOI:10.1080/03081087.2019.1708845]. By using the explicit formula with this setting, the conjectures are therefore proved.

Anđelić-Fonseca 猜想关于某些 Toeplitz 矩阵行列式及其推广的证明
在这项工作中,我们提出并证明了一类的行列式的显式公式非对称 Toeplitz 矩阵。将非零子对角线之一设置为零会产生特殊的五对角 Toeplitz 矩阵,其行列式公式由 Anđelić 和 Fonseca 在 Anđelić 中推测出 [关于五对角矩阵的一些行列式考虑。线性多线性代数。2020. DOI:10.1080/03081087.2019.1708845]。因此,通过使用具有此设置的显式公式,可以证明猜想。
