Vector Lyapunov-like functions for multi-order fractional systems with multiple time-varying delays (Elsevier, 2020)In this paper, a general method to establish the asymptotic behaviour of solutions to multi-order multiple time-varying delays nonlinear systems is proposed. The method, relying on vector Lyapunov-like functions and on ...
