The authors consider the nonlinear functional Volterra integro-differential equation
with multiple delays. They give sufficient conditions so that solutions are bounded, belong to L1, or belong to L2. They also prove the stability and global asymptotic stability of the zero solution. Their technique of proof involves defining appropriate Lyapunov functionals.
