Query: Exponential decay of pairwise correlation in Gaussian graphical models
  with an equicorrelational one-dimensional connection pattern   We consider Gaussian graphical models associated with an equicorrelational
and one-dimensional conditional independence graph. We show that pairwise
correlation decays exponentially as a function of distance. We also provide a
limit when the number of variables tend to infinity and quantify the difference
between the finite and infinite cases.
