We give a bound for the perturbations of invariant subspaces of graded indefinite Hermitian matrix H = D \* AD which is perturbed into H + Ξ΄H = D \* (A + Ξ΄A)D. Such relative perturbations include an important case where H is given with an element-wise relative error. Application of our bounds requir
