DESCRIPTION: \n\n \n\nTITLE\n\nA numerical analyst's journey through spacet
 ime.\n\nABSTRACT\n\nPhysical laws are elegantly described through partial 
 differential equations (PDE). A core concern in numerical analysis is how 
 to achieve high-order approximations of solutions to these PDE. We need to
  ensure our approximation strategy leads to a consistent\, stable and conv
 ergent method. One design principle is that of structure-preservation: our
  discrete problem should respect important underlying structures in the pr
 oblem. These structures could be geometrical\, algebraic\, topological\, a
 nd homological. In this talk I'll introduce the powerful finite element ap
 proach for PDE\, and then motivate the need for the beautiful mathematical
  theory of the finite element exterior calculus. These powerful ideas allo
 w us to describe polynomial differential forms - which themselves form fin
 ite-dimensional subcomplexes of the deRham complex. These are typically de
 scribed on simplicial or tensorial domains. After some concrete examples i
 n R^2 and R^3\, I'll use these ideas to describe recent work on the design
  of high-order discretizations of PDEs in R^4 (space-time problems). I'll 
 present families of conforming high-order finite elements on simplicial el
 ements (these are well-known)\, and also on certain non-simplicial domains
 . The constructions - which are explicit - rely on techniques from the fin
 ite element exterior calculus. This is joint work with David Williams.\n\n
