In the geometric approach some generalized invariant subspaces for uncertain linear systems are investigated, and then various parameter insensitive disturbance-rejection problems with static output feedback are formulated and necessary and sufficient conditions for the problems to be solvable are presented. Further, some sufficient conditions which are useful to check the solvability conditions are presented using the notions of generalized invariant subspaces
