  Title:	High Order Baricentric Tensorial Basas for Triangles and Tetrahedra
  Time/Place:	11:00 a.m., 182 George Street, Room 110

  Abstract:   This talk presents nodal and modal shape functions for triangle and tetrahedron finite elements. The functions are constructed based on fully tensorial expansions of one-dimensional polynomials expressed in baricentric co-ordinates. The nodal functions obtained from the application of the tensorial procedure are the standard h-Lagrange shape functions presented in the literature. The modal shape functions use Jacobi polynomials and have a natural global ${C^0}$ inter-element continuity.
