DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CMWebinar/3/
 ">A discrete elasticity complex on Alfeld splits</a>\nby Johnny Guzman (Br
 own University) as part of Australian Seminar on Computational Mathematics
 \n\n\nAbstract\nWe discuss what appears to be the first finite element ela
 sticity sequence in 3d on tetrahedral meshes.  We build this sequence usin
 g two discrete de Rham sequences that have more smoothness than the Whitne
 y forms. To do this we use Alfeld splits that take a tetrahedral decomposi
 tion and split each tetrahedron into four tetrahedra by adding the barycen
 ter.  We provide degrees of freedom for the spaces as well as commuting pr
 ojections. This is joint work with Snorre Christiansen\, Kaibo Hu and Jay 
 Gopalakrishnan.\n
