On nonoscillation and stability for systems of differential equations with a distributed delay

For the system with a distributed delay Ẋ(t)+∑k=1m∫hk(t)t[dsRk(t,s)]X(s)=0 and a nonnegative fundamental matrix, solution estimates and stability results are obtained. The results are applied to integro–differential equations and equations of mixed type including both distributed and concentrated delays.
