Oscillation criteria for first-order delay equations. (English) Zbl 1035.34075
The authors study the problem of establishing sufficient conditions for the oscillation of the first-order delay differential equation \[ x'(t)+p(t)x(\tau(t))=0 \] under the assumption that \(\lim_{t\to\infty}\int_{\tau(t)}^{t}p(s)\,ds\) does not exist. The obtained results improve related results known in the literature.
