SUMMARY
The notation Z^{*}_{p} refers to the set of integers modulo p that have a multiplicative inverse, specifically defined as Z_{p} - {0}. In ring theory, Z_{p} represents integers under addition modulo p, while Z^{*}_{p} consists of integers from 1 to p-1 under multiplication modulo p. This distinction is crucial as Z^{*}_{p} forms a group with multiplication as the operation, contrasting with the additive structure of Z_{p}.
