Abstract

In this paper, a three-dimensional Legendre polynomial (3D-LPs)
is used for solving the nonlinear three-dimensional Volterra integral equations
(VIEs). Converting the main problem to a nonlinear algebraic system using
3D-LPs which can be generalized to equations in higher dimensions then the
nonlinear system will be solved. A number of results concerning the error analysis
are achieved. Several examples are included to demonstrate the validity and
applicability of the method. Moreover, we prove a theorem and corollary about
sufficient condition for the minimum of mean square error under the Legendre
coefficients and uniqueness of the solution of the nonlinear VIEs. In addition,
illustrative examples are included to demonstrate the validity and applicability
of the presented method.
