Laguerre Spectral Method for High Order Problems

  • Chao Zhang (a1), Ben-Yu Guo (a2) and Tao Sun (a3)


In this paper, we propose the Laguerre spectral method for high order problems with mixed inhomogeneous boundary conditions. It is also available for approximated solutions growing fast at infinity. The spectral accuracy is proved. Numerical results demonstrate its high effectiveness.
