摘要

We study the large deviations of the totally asymmetric zero range processes (TAZRP) on the circle from its hydrodynamic limit with the hyperbolic scaling. First we extend the result of the existence of the hydrodynamic limit from the TAZRP with local Gibbs distributions to the processes with arbitrary deterministic initial configurations.; After establishing a version of the two block estimate with superexponentially small error, we prove the large deviation upper bound by the entropy method initiated in Jensen [3] for the totally asymmetric simple exclusion model. First we follow Kozygina [5] to prove the convergence of the specific entropy of any modified TAZRP with finite process entropy with respect to the TAMP. Then the proof of the upper bound is done by computing explicitly the rate of change of the specific entropy.; We show that the rate function I is supported on the set of weak solutions of the hydrodynamic equation. Furthermore, for any nonentropic weak solution m, the contribution of I(m) from its absolutely continuous part is its deviation from the entropy inequality measured by some fixed entropy-entropy-flux pair (halpha, h˜ alpha), and the contribution from the atomic part is measured by the deviations of the flux out of the site of the delta functions from being maximun. For the continuously singular part lambda(t, du) of m, we have the following partial result: If lambda(t, du ) lambda*(du) for some fixed singular measure lambda*, then its contribution to I(m) is 0 or infinity. Finally at the end of the first chapter we will look at a specific example which attain the lower bound with the same rate function I .
