The relationship between conservation laws and symmetries of space-time is familiar. Here it is shown that in a symmetric background gauge field these conservation laws persist, but in modified form. A further contribution to the conserved quantity occurs. It is determined by the gauge transformati
Symmetries are defined in histories-based theories, paying special attention to the class of history theories admitting quasi-temporal structure (a generalization of the concept of ``temporal sequences'' of ``events'' using partial semigroups) and logic structure for ``single-time histories.'' Symme
