Description : The aim of this monograph is to give a detailed exposition of the summation method that Ramanujan uses in Chapter VI of his second Notebook. This method, presented by Ramanujan as an application of the Euler-MacLaurin formula, is here extended using a difference equation in a space of analytic functions. This provides simple proofs of theorems on the summation of some divergent series. Several examples and applications are given. For numerical evaluation, a formula in terms of convergent series is provided by the use of Newton interpolation. The relation with other summation processes such as those of Borel and Euler is also studied. Finally, in the last chapter, a purely algebraic theory is developed that unifies all these summation processes. This monograph is aimed at graduate students and researchers who have a basic knowledge of analytic function theory.

Description : Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Pages: 23. Chapters: Summability methods, Harmonic series, 1 2 + 3 4 +, Zeta function regularization, 1 2 + 4 8 + ..., 1 + 2 + 4 + 8 + ..., Ces ro summation, Borel summation, Series acceleration, Abelian and tauberian theorems, Grandi's series, Ramanujan summation, 1 + 2 + 3 + 4 + ..., Dimensional regularization, Bochner-Riesz mean, Divergent geometric series, Hadamard regularization, 1 + 1 + 1 + 1 + ..., Lambert summation, Silverman-Toeplitz theorem, Resummation. Excerpt: In mathematics, 1 2 + 3 4 + is the infinite series whose terms are the successive positive integers, given alternating signs. Using sigma summation notation the sum of the first m terms of the series can be expressed as The infinite series diverges, meaning that its sequence of partial sums, does not tend towards any finite limit. Nonetheless, in the mid-18th century, Leonhard Euler wrote what he admitted to be a paradoxical equation: A rigorous explanation of this equation would not arrive until much later. Starting in 1890, Ernesto Ces ro, mile Borel and others investigated well-defined methods to assign generalized sums to divergent series-including new interpretations of Euler's attempts. Many of these summability methods easily assign to a "sum" of after all. Ces ro summation is one of the few methods that do not sum, so the series is an example where a slightly stronger method, such as Abel summation, is required. The series 1 2 + 3 4 + ... is closely related to Grandi's series . Euler treated these two as special cases of for arbitrary n, a line of research extending his work on the Basel problem and leading towards the functional equations of what we now know as the Dirichlet eta function and the Riemann zeta function. The series' terms (1, 2, 3, 4, ...) do not approach 0; therefore diverges by the term test. For later reference, it wil...

Description : “Philosophy is a battle against the bewitchment of our intelligence by means of language.” – Wittgenstein. We use language to think, to talk to each other, to write, to form beliefs, religions, philosophies, and so on. But what if we are using the wrong language? Do we have “wrong thoughts” because we are using the wrong language? Do we have wrong religions and philosophies for exactly the same reason? What’s the right language? If we could find the right language, could we then think correctly, without error, without delusion, without fantasy? Would the right language give us the right religion, the right philosophy? Would it explain reality to us? Discordians hate Truth. The struggle between the Discordians (in all their various forms) and the Illuminati is the most important there is. The soul of humanity is at stake. The Truth itself is the prize to be won or lost.

Description : The letters that Ramanujan wrote to G. H. Hardy on January 16 and February 27, 1913, are two of the most famous letters in the history of mathematics. These and other letters introduced Ramanujan and his remarkable theorems to the world and stimulated much research, especially in the 1920s and 1930s. This book brings together many letters to, from, and about Ramanujan. The letters came from the National Archives in Delhi, the Archives in the State of Tamil Nadu, and a variety of other sources. Helping to orient the reader is the extensive commentary, both mathematical and cultural, by Berndt and Rankin; in particular, they discuss in detail the history, up to the present day, of each mathematical result in the letters. Containing many letters that have never been published before, this book will appeal to those interested in Ramanujan's mathematics as well as those wanting to learn more about the personal side of his life. Ramanujan: Letters and Commentary was selected for the CHOICE list of Outstanding Academic Books for 1996.
