Necessary and sufficient conditions for oscillation of second-order differential equations with nonpositive neutral coefficients [PDF]
Mathematica Bohemica, 2021 In this work, we present necessary and sufficient conditions for oscillation of all solutions of a second-order functional differential equation of type (r(t)(z'(t))^\gamma)' +\sum_{i=1}^m q_i(t)x^{\alpha_i}(\sigma_i(t))=0, \quad t\geq t_0, where ...

Discrete Dynamics in Nature and Society, 2012 We consider the existence for eventually positive solutions of high-order nonlinear neutral differential equations with distributed delay. We use Lebesgue's dominated convergence theorem to obtain new necessary and sufficient condition for the existence ...
