Query: The asymmetric simple exclusion process with an open boundary   We consider the asymmetric simple exclusion process confined to the
nonnegative integers with an open boundary at 0. The point 0 is connected to a
reservoir where particles are injected and ejected at prescribed rates subject
to the exclusion rule. We derive formulas for the transition probability as a
function of time from states where initially there are m particles to states
where there are n particles.
