There has been relatively little interaction between the numerical relativists carrying out this research program and mathematically oriented general relativists. Yet, a number of issues have arisen where further input from mathematical general relativists might be of great use. One example of such an issue is the form in which Einstein's equation is expressed: Do hyperbolic formulations have advantages over non-hyperbolic formulations? If so, which hyperbolic formulations are "best"? Another major issue involves the choice of coordinate and time slicing conditions: If one chooses a slicing so as to avoid the physical singularities produced by the collapse, severe "grid stretching" difficulties arise. These are presently being dealt with by excising the black hole from the spacetime, but present procedures remain rather rudimentary and undeveloped.

The goal of this miniprogram is be to bring together numerical relativists and mathematical general relativists to discuss these and other issues related to the black hole collision problem.
