Effective solution of nonlinear DAEs problems using Taylor series method
Most methods for solving ordinary differential equations use a limited order to calculate the results. The higher-order method based on the Taylor series presented in this article can use as many terms of the Taylor series as necessary to obtain a stable

Dynamic ecological system measures
The system decomposition theory has recently been developed for the dynamic analysis of nonlinear compartmental systems. The application of this theory to the ecosystem analysis has also been introduced in a separate article.

A Study on Iterative Solution of Population Dynamics Models
In this paper, simple approximate solutions of differential equations pertaining to population dynamics are obtained using iterative method. When the order of approximation tends to infinity, the solutions obtained converge towards an exact solution in ...

Generic polynomial vector fields are not integrable *
We study some generic aspects of polynomial vector fields or polynomial derivations with respect to their integration. In particular, using a well-suited presentation of Darboux polynomials at some Darboux point as power series in local Darboux ...

Langevin equation in terms of conformable differential operators
In this paper, we establish sufficient criteria for the existence of solutions for a new kind of nonlinear Langevin equation involving conformable differential operators of different orders and equipped with integral boundary conditions.

Approximating solutions of Hammerstein Type equations in Banach Spaces
Let X be a real Banach space and X* be its dual. Let F : X → X* and K : X → X* be Lipschitz monotone mappings. In this paper an explicit iterative scheme is constructed for approximating solutions of the Hammerstein type equation, 0 = u + KFu; when they ...

Nonlinear Hamiltonian systems and exponential asymptotics for the adiabatic invariants
In this paper, for a symmetric nonlinear oscillator, we show that to the leading order, the adiabatic invariant is equivalent to the quantity y'(0), where y is a family of adiabatically symmetric solutions. The leading order of the latter quantity can be
