Query: On zero-rate error exponents of finite-state channels with
  input-dependent states   We derive a single-letter formula for the zero-rate reliability (error
exponent) of a finite-state channel whose state variable depends
deterministically (and recursively) on past channel inputs, where the code
complies with a given channel input constraint. Special attention is then
devoted to the important special case of the Gaussian channel with inter-symbol
interference (ISI), where more explicit results are obtained.
