Abstract
An overview of recent results in nonsmooth analysis and control theory, with particular emphasis on proximal methods, is presented. The topics covered include proximal aiming and weak invariance (this being the core concept for many of the subsequent results presented), monotonicity along trajectories and Lyapunov stabilization, feedback synthesis in optimal control, existence of equilibria under invariance hypotheses, set smoothings and approximations, differential inequalities, and invariance theory in Hilbert space.
