The stationary measure of a 2-type totally asymmetric exclusion process. (English) Zbl 1087.60067

Summary: We give a combinatorial description of the stationary measure for a totally asymmetric exclusion process (TASEP) with second class particles, on either \(\mathbb Z\) or on the cycle \(\mathbb Z_{N}\). The measure is the image by a simple operation of the uniform measure on some larger finite state space. This reveals a combinatorial structure at work behind several results on the TASEP with second class particles.
