In this paper, a numerical method which produces an approximate polynomial solution is
presented for solving Lane–Emden equations as singular initial value problems. Firstly, we …

This paper presents a new approximate method of Abel differential equation. By using the
shifted Chebyshev expansion of the unknown function, Abel differential equation is …

In this paper, we consider differential-algebraic equations (DAEs) systems. The approximate
solutions for the differential-algebraic equations (DAEs) systems are obtained by using the …

In this paper, numerical solution of differential–algebraic equations (DAEs) with index-2 has
