Stable and Efficient Spectral Methods in Unbounded Domains Using Laguerre Functions∗

  • N SIAMJ.
  • Published 2000


Stable and efficient spectral methods using Laguerre functions are proposed and analyzed for model elliptic equations on regular unbounded domains. It is shown that spectral-Galerkin approximations based on Laguerre functions are stable and convergent with spectral accuracy in the usual (not weighted) Sobolev spaces. Efficient, accurate, and well… (More)
