Abstract: 

Associated to any finite rack X is an associative algebra known as the rack algebra Z[X], originally defined in 2003 by Andruskiewitsch and Grana. Representations of Z[X], known as rack modules, can be used to refine and enhance the rack counting invariant. Time permitting, we will also consider a few generalizations of the rack algebra.
