摘要
In this paper we investigate the Ulam-Hyers stability of first order differential systems with nonlocal initial conditions on compact intervals (in W-1,W-1(0, k)) and on noncompact intervals (in W-w(1,2)(0,infinity), with suitable weight function w). The novelty consists in the simultaneous use of vectorial norms, convergent to zero matrices, Sobolev spaces for studying the Ulam- Hyers stability of equations with nonlocal conditions on noncompact intervals.
