Sextic spline collocation methods for nonlinear fifth-order boundary value problems. (English) Zbl 1230.65086

The authors develop two sextic-spline collocation methods for approximating solutions of nonlinear fifth-order boundary-value problems. The first method uses a spline interpolant and the second one is based on a spline quasi-interpolant, which are constructed from sextic splines. Numerical examples confirm the second-order convergence predicted by the theoretical analysis.
