Cramer's rules for Hermitian systems of coquaternionic equations

In this paper properties of the determinant of a Hermitian matrix are investigated, and determinantal representations of the inverse of a Hermitian coquaternionic matrix are given. By their using, Cramer’s rules for left and right systems of linear equations with Hermitian coquaternionic matrices of coefficients are obtained. Cramer’s rule for a two-sided coquaternionic matrix equation $\mathbf{A}\mathbf{X}\mathbf{B}=\mathbf{D}$ (with Hermitian $\mathbf{A}$, $\mathbf{B}$) is given as well.
