Query: Khintchine-Pollaczek formula for random walks whose steps have one
  geometric tail   We derive a Khinchine-Pollaczek formula for random walks whose steps have a
geometric left tail. The construction rests on the memory-less property of the
geometric distribution. An example from a tandem queue modeling dynamic
instability in microtubules is given.
