- Abstract
The nonlinear space time dynamics have been discussed in terms of a hyperbolic equation known as a sine-Gordon equation. The proposed equation has been discretized using the Bessel collocation method with Bessel polynomials as base functions. The proposed hyperbolic equation has been transformed into a system of parabolic equations using a continuously differentiable function. The system of equations involves one linear and the other nonlinear diffusion equation. The convergence of the present technique has been discussed through absolute error, L2-norm, and L∞-norm. The numerical values obtained from the Bessel collocation method have been compared with the values already given in the literature. The present technique has been applied to different problems to check its applicability. Numerical values obtained from the Bessel collocation method have been presented in tabular as well as in graphical form.
