We consider the problem of existence and structure of solutions bounded on the entire real axis of nonhomogeneous linear impulsive differential systems. Under assumption that the corresponding homogeneous system is exponentially dichotomous on the semiaxes R- and R and by using the theory of pseudoinverse matrices we establish necessary and sufficient conditions for the indicated problem. The research in the theory of differential systems with impulsive action was originated by Myshkis and Samoilenko 1 Samoilenko and Perestyuk 2 Halanay and Wexler 3 and Schwabik et al. 4 . The ideas proposed in these works were developed and generalized in numerous other publications 5 . The aim of this contribution is using the theory of impulsive differential equations using the well-known results on the splitting index by Sacker 6 and by Palmer 7 on the Fredholm property of the problem of bounded solutions and using the theory of pseudoinverse matrices 5 8 to investigate in a relevant space the existence of solutions bounded on the entire real axis of linear differential systems with impulsive action. We consider the problem of existence and construction of solutions bounded on the entire real axis of linear .
