Qualitative Behavior of the Solutions to Delay and Difference Equations
Вестник КазНУ. Серия математика, механика, информатика, 2018 It is noteworthy to observe that a first-order linear ordinary differential equation without delay does not possess oscillatory solutions. Therefore the investigation of oscillatory solutions is of interest for equations with delays or for the discrete

Dynamics of Bianchi type I elastic spacetimes
, 2007 We study the global dynamical behavior of spatially homogeneous solutions of the Einstein equations in Bianchi type I symmetry, where we use non-tilted elastic matter as an anisotropic matter model that naturally generalizes perfect fluids.

On a class of fourth order linear recurrence equations
International Journal of Mathematics and Mathematical Sciences, 1984 This paper is concerned with sequences that satisfy a class of fourth order linear recurrence equations. Basic properties of such sequences are derived. In addition, we discuss the oscillatory and nonoscillatory behavior of such sequences.

Oscillation of solutions to second-order nonlinear differential equations of generalized Euler type
Electronic Journal of Differential Equations, 2013 We are concerned with the oscillatory behavior of the solutions of a generalized Euler differential equation where the nonlinearities satisfy smoothness conditions which guarantee the uniqueness of solutions of initial value problems, however, no ...
