Abstract
Two sufficient conditions under which the roots of the determinant of a given ( 
) matrix polynomial of 
th order lie in the open left-half plane have been obtained. The first condition is given in terms of the positive definiteness of an ( 
) symmetric matrix, while the second condition is given in terms of the positive definiteness of an ( ) matrix that is a function of 
, Re 
. These conditions are represented in terms of rational functions of the coefficient matrices of the given matrix polynomial. Therefore, the explicit computation of the determinant polynomial is not required.
