【Abstract】 The problem of eigenvalue for the single symmetric positive definite solution \$X\$ of discrete time algebra Riccati equation (DTARE) is studied. Through identical deformation of matrix, a new analytical method is given. Finally, the upper and the lower bound of the extreme eigenvalue for the solution \$X\$ of DTARE and a lower bound of trace for the solution \$X\$ of DTARE can be obtained.\;
