\section{Singular systems, state feedback problem} By {\sl Marija Dodig}.  

\medskip  \noindent In this talk, the strict equivalence invariants by state feedback  for singular systems are studied. As the main result we give  the necessary and sufficient conditions under which there exists a state feedback such that the resulting system  has prescribed pole structure as well as row and column minimal indices. This result presents a generalization of  previous results of state feedback action on singular systems.
