In 1914 S. Ramanujan recorded a list of 17 series for 1=…. We survey the methods of proofs of Ramanujan’s formulae and indicate recently discovered generalisations, some of which are not yet proven. Let us start with two signiflcant events of the 20th century, in the opposite historical order. At flrst glance, the stories might be thought of a difierent nature. 
A method for proving Ramanujan’s series for $$1/\pi $$1/π
In a famous paper of 1914 Ramanujan gave a list of 17 extraordinary formulas for the number $$1/\pi $$1/π. In this paper we explain a general method to prove them, based on some ideas of James WanExpand

Abstract A general theorem is stated that unifies 93 rational Ramanujan-type series for 1/π, 40 of which are believed to be new. Moreover, each series is shown to have a companion identity, therebyExpand
Divergent Ramanujan-type supercongruences
"Divergent" Ramanujan-type series for $1/\pi$ and $1/\pi^2$ provide us with new nice examples of supercongruences of the same kind as those related to the convergent cases. In this paper we manage toExpand
Kind of proofs of Ramanujan-like series
We make a summary of the different types of proofs adding some new ideas. In addition we conjecture some relations which could be necessary in "modular type proofs" (not still found) of theExpand
Mosaic Supercongruences of Ramanujan Type
Congruences of supercongruences of Ramanujan type observed by L. Van Hamme and W. Zudilin are presented, inspired by Ramanuja-type series that involve quadratic algebraic numbers. Expand
A new Ramanujan-like series for $1/\pi^2$
Our main results are a WZ-proof of a new Ramanujan-like series for $1/\pi^2$ and a hypergeometric identity involving three series.
Ramanujan-type supercongruences
Abstract We present several supercongruences that may be viewed as p-adic analogues of Ramanujan-type series for 1 / π and 1 / π 2 , and prove three of these examples.
On the (K.2) supercongruence of Van Hamme
Abstract We prove the last remaining case of the original 13 Ramanujan-type supercongruence conjectures due to Van Hamme from 1997. The proof utilizes classical congruences and a WZ pair due toExpand
Lost in translation
The principal goal of this note is to set some grounds about applicability of algebraic transformations of (arithmetic) hypergeometric series for proving Ramanujan’s formulae for 1/π and theirExpand
Sporadic sequences, modular forms and new series for 1/π
Two new sequences, which are analogues of six sporadic examples of D. Zagier, are presented. The connection with modular forms is established and some new series for 1/π are deduced. The experimentalExpand


Domb's numbers and Ramanujan–Sato type series for 1/π
Abstract In this article, we construct a general series for 1 π . We indicate that Ramanujan's 1 π -series are all special cases of this general series and we end the paper with a new class of 1 πExpand
Ramanujan-type formulae and irrationality measures of some multiples of $ {\pi}$
An explicit construction of simultaneous Pade approximations for gener- alized hypergeometric series and formulae for the quantities π √ d , d ∈{ 1, 2, 3, 10005}, in terms of these series are usedExpand
More Ramanujan-type formulae for 1/π²
Some of the most spectacular achievements in the history of the number π are the representations of 1/π by rapidly converging series discovered by Ramanujan [1] in 1914. Although Ramanujan himselfExpand
Ramanujan's Class Invariant λn and a New Class of Series for 1/π
On page 212 of his lost notebook, Ramanujan defined a new class invariant λ n and constructed a table of values for λ n . The paper constructs a new class of series for 1/π associated with λ n . TheExpand
A WZ proof of Ramanujan's Formula for Pi
Ramanujan's series for Pi, that appeared in his famous letter to Hardy, is given a one-line WZ proof.
Generators of some Ramanujan formulas
In this paper we prove some Ramanujan type formulas for 1/π but without using the theory of modular forms. Instead we use the WZ—method created by H. Wilf and D. Zeilberger and find someExpand
About a New Kind of Ramanujan-Type Series
A new kind of Ramanujan-type formula for 1/π is proposed and it is conjectured that it is related to the theory of modular functions. Expand
A Proof that Euler Missed...
The board of programme changes informed us that R. Apery (Caen) would speak Thursday, 14.00 “Sur l’irrationalite de ζ(3).” Though there had been earlier rumours of his claiming a proof, scepticismExpand
Tables of Calabi-Yau equations
The main part of this paper is a big table (see Appendix A) containing what we believe to be a complete list of all fourth order equations of Calabi–Yau type known so far. In the text preceding theExpand
Hypergeometric series acceleration via the WZ method
Based on the WZ method, some series acceleration formulas are given. These formulas allow us to write down an inflnite family of parametrized identities from any given identity of WZ type. Further,Expand
