Improved Hille-Type Oscillation Criteria for Second-Order Quasilinear Dynamic Equations
Mathematics, 2022 In this work, we develop enhanced Hille-type oscillation conditions for arbitrary-time, second-order quasilinear functional dynamic equations. These findings extend and improve previous research that has been published in the literature.

The logistic equation in the context of Stieltjes differential and integral equations
Electronic Journal of Qualitative Theory of Differential Equations, 2023 In this paper, we introduce logistic equations with Stieltjes derivatives and provide explicit solution formulas. As an application, we present a population model which involves intraspecific competition, periods of hibernation, as well as seasonal ...

Equations of fluid dynamics with the l-conformal Galilei symmetry [PDF]
, 2022 Equations of fluid dynamics are formulated, which hold invariant under the action of the l-conformal Galilei group. They include the conventional continuity equation, a higher order material derivative analogue of the Euler equation, and a suitable modification of the conventional equation of state.
