We study the properties of reachable sets of control systems that are linear in control. For the reachable sets of a certain class of such systems, we estimate the growth of their degree of nonconvexity $\alpha $ over time. As an auxiliary result, we establish a relationship between $\alpha $-sets and weakly convex sets in the sense of Vial.
Keywords: Generalized convex set, weakly convex set, reachable set, control system.
Mots-clés : $\alpha $-set
