1 A new proof of a q-continued fraction of Ramanujan Gaurav Bhatnagar (Wien) SLC 77, Strobl, Sept 13, 2016
2 It is hoped that others will attempt to discover the pathways that Ramanujan took on his journey through his luxuriant labyrinthine forest of enchanting and alluring formulas. Bruce Berndt (Page 1, Ramanujan s Notebooks, Part III)
3 Goal Ch. 16, Entry 11, 12 Notebook 2 (Part III, Berndt)
4 Ch. 16, Entry 11, Notebook 2 (Part III, Berndt) Goal Ch. 16, Entry 12
5 The approach comes from
6 Euler s approach N D =1+N D D 1+a 1 x + a 2 x 2 + a 3 x b 1 x + b 2 x 2 + b 3 x 3 + =1+(1 + a 1x + a 2 x 2 + ) (1 + b 1 x + b 2 x 2 + ) 1+b 1 x + b 2 x 2 + b 3 x 3 +
7 Example 1. The Rogers-Ramanujan Continued fraction Cor. Entry 15, Chapter 16, Notebook 2, Part 3 Y 8 >< >: q k2 +k X q k2 = aq aq 2 1+ aq3 1+ where (a; q) n := Y (1 aq j ) n 1 j=0
8 The (formal) proof Divide! 1+ q k2 +k q k2 1 q k2 = q k2 +k 1 q k2 q k2 +k q k2 +k N D =1+N D D
9 Consider the difference of sums q k2 q k2 +k = q k2 (1 q k ) k=1 q k2 (1 q k )= = k=1 = aq q k2 1 q (k+1)2 +1 q k2 +2k
10 1+ aq 1 q k2 +2k q k2 +k = 1 1+ aq q k2 +k q k2 +2k
11 aq q k2 +k (1 q k ) q k2 +2k N D =1+N D D q k2 +k (1 q k )= = k=1 = aq 2 q k2 +k 1 q (k+1)2 +k+1 +1 q k2 +3k
12 1 1+ aq 1+ aq 2 q k2 +2k q k2 +3k
13 In general: R(s) := q k2 +sk R(1) R(0) = 1 R(0) R(s) R(s + 1) =1+ R(1) = 1 1+ Take limits to complete (formal) proof. aq 1+ aqs+1 R(s + 1) R(s + 2) aq aq s+1 R(s + 1) R(s + 2)
14 Notes Note this calculation: When we shift the index, a few terms come out of the sum, because we want the sum to have first term 1 These sums can be written as infinite products. These are the famous Rogers-Ramanujan identities
15 Rogers-Ramanujan Identities
16 Example 2 Want a continued fraction where we know that the sums can be written in terms of infinite products. We can think of using the q-binomial theorem, the simplest example of a sum written as a ratio of products. Here s one approach.
17 Example 2. Entry 11 Entry 3. The q-binomial theorem Ratio of odd part/even part of series
18 Entry 11- Product side Rewrite the products to get one side of Entry 11
19 The ratio can be written as Ratio of sums
20 Recall Apply Euler s approach
21 Apply Euler s approach
22 So we get Again, apply Euler s approach to the ratio of two series
23
24 Pattern is clear now. We get
25 Iterate to obtain
26 Proposition: A finite form of Entry 11 For: As s goes to infinity, we get Modified Covnergence of the infinite continued fraction of Entry 11
27 Next Entry 11 involves One can ask: Is there a similar continued fraction with even powers? We had in the denominator. One can try with In view of the q-binomial theorem, one can try with sums of the type:
28 After some messing around, we end up with The calculations involved become We use On shifting index, we will get We get So we take and squares of other parameters too, and make some more minor adjustments.
29 Example 3: Entry 12 We begin with Product side is OK. One can now try what happens in Euler s approach.
30 Entry 12: Euler s approach We begin with We use
31
32 Some issues So we add and subtract enough terms to get this factor and see what happens
33 So we add and subtract enough terms to get this factor and see what happens

38 The pattern is clear now.

40 Proposition: A finite form of Entry 12 As s goes to infinity, we get Modified Covnergence of the infinite continued fraction of Entry 12 For:
41 Overview Entry 11: Was first proved by Adiga, Berndt, Bhargava and Watson (1985) Used Heine s continued fraction, q-binomial theorem Entry 12: Adiga, Berndt, Bhargava and Watson (1985), Jacobsen (1989), Ramanathan (1987) Adiga, Berndt et.al. thank Askey and Bressoud for ideas on how to prove Entry 12. Used Heine s continued fraction, Heine s transformation, Bailey-Daum summation Our proof uses only the q-binomial theorem, which is Entry 2 in chapter 16 of Ramanujan s second notebook (Berndt, Part III) It s a discovery proof. Given Ramanujan s talents, not too farfetched to think he may have thought like this.
42 I have often been asked whether Ramanujan had any special secret; whether his methods differed in kind from those of other mathematicians; whether there was anything really abnormal in his mode of thought. I cannot answer these questions with any confidence or conviction; but I do not believe it. My belief is that all mathematicians think, at bottom, in the same kind of way, and that Ramanujan was no exception. G. H. Hardy
