Abstract:

The oscillation of second\|order neutral delay differential equations with distributed deviating argument, a class of new functions Φ(t,s,l) and the function cl
ass F, we relaxed the restriction on function f, namely, when f does not satisfy the following conditions: there exists M>0, such that (f(±uv))≥Mf(u)f(v), uv>0, and hence established some new oscillation criteria for secondorder neutral equations with distributed deviating argument. An example was given to illustrate the results.

Key words: oscillation, neutral delay differential equation, distributed deviating argument
