High-order accuracy approximation for a two-point boundary value problem of fourth order with degenerate coefficients
The authors propose a high-order finite element scheme for a fourth-order ordinary differential equation with degenerate coefficients. The proposed method is based on multiplicative and additive-multiplicative separation of singularities. Some a-priori error bounds are also proved. No numerical example is given.
