On The Chaotic Asymptotics of Ramanujan's Entire Function $A_q(z)$

On A Limiting Relation Between Ramanujan's Entire Function $A_{q}(z)$ And $θ$-Function

We will use a discrete analogue of the classical Laplace method to show that the main term of the asymptotic expansions of certain entire functions, including Ramanujan's entire function $A_{q}(z)$, can be expressed in terms of $θ$-functions.

Zeros of Ramanujan Type Entire Functions

In this work we establish some polynomials and entire functions have only real zeros. These polynomials generalize q-Laguerre polynomials $L_{n}^{(α)}(x;q)$, while the entire functions are generalizations of Ramanujan's entire function $A_{q}(z)$, q-Bessel functions $J_ν^{(2)}(z;q)$, $J_ν^{(3)}(z;q)$ and confluent basic hypergeometric series.

Ramanujan's Beautiful Integrals

Throughout his entire mathematical life, Ramanujan loved to evaluate definite integrals. One can find them in his problems submitted to the \emph{Journal of the Indian Mathematical Society}, notebooks, Quarterly Reports to the University of Madras, letters to Hardy, published papers and the Lost Notebook. His evaluations are often surprising, beautiful, elegant, and useful in other mathematical contexts. He also discovered general methods for evaluating and approximating integrals. A survey of Ramanujan's contributions to the evaluation of integrals is given, with examples provided from each o…
