Some new oscillation criteria are established for a second order neutral partial functional differential equation.Assumptions in our theorems are less restrictive,also the proofs are simpler than those in Li and Cui [...

We establish explicit bounds on some more general retarded integral inequalities which can be used as convenient tools in some applications, and give some examples which show the feasibility of our results.
