|Bruce's Return gift: A daily reminder of Ramanujan|
In June, 2019, I attended a very inspiring conference, held at the University of Illinois at Urbana-Champaign. This was to celebrate Bruce Berndt's 80th birthday and his retirement. Bruce is the greatest living expert on Ramanujan and one of the nicest people in the world. He is scholarly and an inspiration. His retirement means nothing, he is already traveling around the world and he said he is working on another book with Ae Ja Yee on partitions. My wishes to him were more for myself than for him: Wishing us many, many books and papers from you for many, many years!
Mourad Ismail and I have written a paper for the occasion. I presented it in Illinois in front of a small audience, which included Bruce. This is the second paper with Mourad on the subject of Ramanujan's continued fractions, using techniques he has taught me. I gave a talk on this continued fraction in 2016, in SLC 77. The talk is available here: https://www.mat.univie.ac.at/~

Title: On Entry II.16.12: A continued fraction of Ramanujan
Authors: Gaurav Bhatnagar and Mourad E. H. Ismail
Comments: 15 Pages
MSC-class: 33D45 (Primary), 30B70 (Secondary)
We study a continued fraction due to Ramanujan, that he recorded as Entry 12Here is a picture taken at the Banquet.
in Chapter 16 of his second notebook. It is presented in Part III of Berndt's
volumes on Ramanujan's notebooks. We give two alternate approaches to proving Ramanujan's Entry 12, one using a method of Euler, and another using the theory of orthogonal polynomials. We consider a natural generalization of Entry 12 suggested by the theory of orthogonal polynomials.

I presented this work in the OPSFA2019 conference in Hagenberg, Austria. Here are the slides from the talk in Hagenberg. OPSFA2019 was an amazing conference. I got a chance to hear Christian's concert on the church organ, saw and heard Chihara, met Alan Sokal (among others), hung out with Michael and Hjalmar and worked with Mourad on this paper and on our next joint paper. Here is a picture from Hagenberg.
