We propose diverse upper bounds for the solution matrix of the continuous algebraic Riccati matrix equation (CARE) by building the equivalent form of the CARE and using some matrix inequalities and linear algebraic techniques. Finally, numerical exam

We first present an inequality for the Frobenius norm of the Hadamard product of two any square matrices and positive semidefinite matrices. Then, we obtain a trace inequality for products of two positive semidefinite block matrices by using 2×2 blo

We present some lower bounds for the Frobenius condition number of a positive definite matrix depending on trace, determinant, and Frobenius norm of a positive definite matrix and compare these results with other results. Also, we give a relation for

It is obtained that for positive semidefinite block matrix H = [ M K K ⁎ N ] if A , B ∈ M n ( C ) such that m a x ( ‖ A ‖ 2 , ‖ B ‖ 2 ) ≤ 2 and f is a nonnegative increasing convex function on [ 0 , ∞ ) satisfying f ( 0 ) = 0 , then 2
