Mountford, Thomas et Guiol, Hervé, The motion of a second class particle for the tasep starting from a decreasing shock profile, Annals of applied probability , 15(2), 2005, pp. 1227-1259
We prove a strong law of large numbers for the location of the second class particle in a totally asymmetric exclusion process when the process is started initially from a decreasing shock. This completes a study initiated in Ferrari and Kipnis [Ann. Inst. H. Poincaré Probab. Statist. 13 (1995) 143.154].
