AB - <p style="text-align: justify;">This work is concerned with the nonlinear matrix equation $X^s + A^*F(X)A= Q$ with $s ≥ 1$. Several sufficient and necessary conditions for the existence and &nbsp;uniqueness of the Hermitian positive semidefinite solution are derived, and perturbation bounds are presented.</p>
