Title: Computational Aspects of Mesh-free Discretizations

Abstract: 

In this talk I will discuss a variety of topics involved in the assembly
and solution of sparse linear systems arising from Mesh-free discretizations. 
Mesh-free methods have been used in Engineering to avoid difficulties with
mesh generation that occur in traditional finite element methods. 
Some topics I will discuss include new matrix assembly techniques, 
fast linear solvers and data structures which should be used for 
these problems.
