DESCRIPTION:Title: The ultraspherical spectral method\n	\n	Abstract: Pseudosp
 ectral methods\, based on high degree polynomials\, have spectral accuracy
  when solving differential equations but typically lead to dense and ill-c
 onditioned matrices. The ultraspherical spectral method is a numerical tec
 hnique to solve ordinary and partial differential equations\, leading to a
 lmost banded well-conditioned linear systems while maintaining spectral ac
 curacy. In this talk\, we introduce the ultraspherical spectral method and
  develop it into a spectral element method using a modification to a hiera
 rchical Poincaré-Steklov domain decomposition method.\n
