M.S. Paper Title:  Enabling Unstructured Multigrid Under the Sieve  
Framework

Abstract:
Geometric multigrid methods greatly accelerate the convergence of  
finite element systems by using a series of coarser meshes to  
efficiently remove persistent error from the solution.  Motivated by  
boundary value problems requiring vastly changing refinement scales on  
different parts of the finest mesh, a flexible geometric technique for  
coarsening simplicial meshes is adapted to sieve, a topologically- 
motivated mesh framework.  This combination leads to an efficient  
method for building hierarchies of quality meshes that are suitable  
for multigrid methods on complex domains in 2D and 3D.

Advisors:  Professors L. Ridgway Scott and Todd Dupont
