“…A frequently used method for solving the controllability problem is to transform it into a fixed point problem for an appropriate operator in a function space. Existence and control problems for various types of measure differential systems have been studied by many authors in [2,3,4,7,14,25,34,38,42]. For example, Gou and Li [7] investigated the controllability of semi-linear MEDs by applying Schauder's fixed point theorem.…”
