“…The 2 celebrated results given by Gronwall, Bellman, Bihari and their linear and nonlinear generaliza-Q2 3 tions in the case of continuous and discontinuous functions provide a fundamental role in the 4 study of many qualitative properties of differential and integral equations, which we can find in 5 [3,6,4,11,12,15-17,2, 1,10,9]. For some new development on this topic, see [5,8,13,18,14,19,7]. 6 In 2007, Jiang and Meng [8] discussed the following delay integral inequalities:…”
