Abstract:
A numerical method based on Legendre multi-wavelets is applied for solving
Lane-Emden equations which form Volterra integro-differential equations.
The Lane-Emden equations are converted to Volterra integro-differential
equations and then are solved by the Legendre multi-wavelet method.
The properties of Legendre multi-wavelets are first presented.
The properties of Legendre multi-wavelets are used to reduce the system of
integral equations to a system of algebraic equations which can be solved
by any numerical method. Illustrative examples are discussed to show
the validity and applicability of the present method.
