Abstract:
In this project report, singular initial value problems, linear and non-linear, homogeneous and
non-homogeneous of Lane-Emden-type equations are solved by using Taylor series, Residualpower
series,
and
Adomain
decomposition
methods.
To
apply
these methods; the Lane-Emdentype
equation is solved analytically in the presence of singular point at x=0, to generate results
for higher order derivatives and it shows a form of convergent series of the solution.
The class of singular equation was generalized by changing the coefficient of
, and the
proposed technique was presented in a general way. The methods are illustrated with some
examples, to yield exact results; several test problems have been presented to demonstrate the
variability and practical usefulness of the methods. From these methods; ADM gives a better
rapid convergent series with components that are elegantly computed to the solution. It is
observed that the methods are easy to implement, valuable for handling singular phenomena,
yields exact solution with easily computable terms.
