Asymptotic Stability of Solutions to a Class of Second-Order Delay Differential Equations

Mathematics, 2021
We consider a class of second-order nonlinear delay differential equations with periodic coefficients in linear terms. We obtain conditions under which the zero solution is asymptotically stable. Estimates for attraction sets and decay rates of solutions

On the Cauchy Problem for Pseudohyperbolic Equations with Lower Order Terms

Mathematics, 2023
We consider a class of strictly pseudohyperbolic equations with lower order terms. The solvability of the Cauchy problem in Sobolev spaces with special weights is established. The uniqueness of the solution is proven and estimates are obtained.

Asymptotic Properties of Solutions to Delay Differential Equations Describing Plankton—Fish Interaction

Mathematics, 2021
We consider a system of differential equations with two delays describing plankton–fish interaction. We analyze the case when the equilibrium point of this system corresponding to the presence of only phytoplankton and the absence of zooplankton and fish
