On the Growth and Oscillation of Fixed Points of Solutions of Linear Differential Equations with Merhigher order complex linear differential equations with meromorphic coefficients. We describe the relationship in terms of growth and exponent of convergence between the solutions and the coefficients of differential equations. Some previous results considering the concept of iterated order will be improved and extended.

A Note On a Prey-Predator Model with Constant-Effort Harvesting Our goal is twofold: to present the model proposed by Cheng and Zhang in 2021, pointing out some inconsistencies; to analyse the number and type of equilibrium points of the model. We end by proving the stability of the meaningful equilibrium point, according to the distribution of the eigenvalues.

Lieder,ee (i.e. incompressible) vector field, when the phase space is the whole Euclidean space and the vector field satisfies so-called vanishing mean drift condition. For the case when the ODE is defined over some smooth compact connected Riemannian manifold, we significantly strengthen the assertion of

Nachwort, consider four state variables: ., ., . and .. The variable . represents the quantity of water in the .th quarter of the radical depth of the soil, where .. We consider a single control which represents the flow of water introduced in the soil via its irrigation system, directly on the surface layer

Approximations of various orders are construc

The population is exploited by both the permanent harvesting and periodic impulse harvesting of some constant parts of the resource density. We prove that there exist the admissible harvesting strategy and the initial distribution of the resource that provide the maximum

The considered approach is the asymptotic decomposition of the system, depending on the two small parameters of singular perturbati
