Suppose b(1) = 1 and b(n+1) = +-b(n) +- x*b(n-1) with the four choices of sign made with equal probability. Embree and Trefethen show that if x is less than this constant, b(n) tends to 0; otherwise, |b(n)| increases without bound. - Charles R Greathouse IV, Jul 19 2013
Named after the American mathematicians Mark Patrick Embree (b. 1974) and Lloyd Nicholas Trefethen (b. 1955). - Amiram Eldar, Jun 16 2021
