Abstract
A careful study on the mesoscopic PC in a Luttinger liquid ring is carried out. It is shown that discreteness plays an important role in calculating the PC caused by the magnetic flux. At zero temperature, the current is shown to be independent of the interaction even when is not zero. The current becomes enhanced at finite temperatures comparing to the non-interacting case, when the parameter g is positive.
