  "abstract": "We prove converse Lyapunov theorems for input-to-state stability (ISS) of a broad class of infinite-dimensional systems applicable to evolution equations in Banach spaces, boundary control systems, and delay systems. To this end, we employ a novel method that does not require constructing auxiliary closed-loop systems. We start by showing that ISS of a control system implies uniform global asymptotic stability of the same system with respect to trajectory-dominated inputs. Then, under an additional regularity requirement, we prove that an ISS Lyapunov function can be constructed. Based on our general result, we prove that for linear systems with unbounded $\\infty$-admissible operators, ISS is equivalent to the existence of a Lipschitz continuous coercive ISS Lyapunov function.",
