On The Chaotic Asymptotics of Ramanujan's Entire Function $A_q(z)$
  We will use a discrete analogue of the classical \emph{Laplace} method to show that for infinitely many positive integers $n$, the main term of the asymptotic expansions of scaled confluent basic hypergeometric functions, including the Ramanujan's entire function $A_{q}(z)$, could be expressed in $\theta$-functions, and the error term depends on the ergodic property of certain real scaling parameter.
