Begehr, H. G. W. (ed.) et al., Further progress in analysis. Proceedings of the 6th international ISAAC congress, Ankara, Turkey, August 13–18, 2007. Hackensack, NJ: World Scientific (ISBN 978-981-283-732-5/hbk). 507-514 (2009).
Summary: Using a Riccati-type transformation and the integral averaging technique, some new oscillation criteria for third-order delay differential equations of the form
\[ (r_2(t)(r_1(t)y')')'+p(t)y'+q(t)r(y(g(t)))=0 \]
are established.
For the entire collection see [Zbl 1169.00010].
