Efficient Distributed Cross Match Queries in the Virtual Observatory

The problem of cross matching astronomical catalogs for information of interest is a non-trivial problem requiring complex mathematical computations for comparison of each pair of objects in the sky. A discussion would be presented on the different strategies used for performing efficient cross matching of astronomical objects, thereby stating their advantages and disadvantages as well as presenting respective experimental results.
