Among these papers, Andrews discovered a sheaf of pages in the handwriting of Srinivasa Ramanujan. This manuscript was soon designated, "Ramanujan's lost notebook. This fifth and final installment of the authors' examination of Ramanujan's lost notebook focuses on the mock theta functions first introduced in Ramanujan's famous Last Letter. This volume proves all of the assertions about mock theta functions in the lost notebook and in the Last Letter, particularly the celebrated mock theta conjectures.

Other topics feature Ramanujan's many elegant Euler products and the remaining entries on continued fractions not discussed in the preceding volumes. Review from the second volume: "Fans of Ramanujan's mathematics are sure to be delighted by this book.

While some of the content is taken directly from published papers, most chapters contain new material and some previously published proofs have been improved. Many entries are just begging for further study and will undoubtedly be inspiring research for decades to come. The next installment in this series is eagerly awaited.

### Ramanujan’s lost notebook: part I (2005)

This is the first step…on the way to an understanding of the work of the genius Ramanujan. It should act as an inspiration to future generations of mathematicians to tackle a job that will never be complete. Ramanujan's lost notebook : Part V. Ramanujan's lost notebook Part V. This is the first step It should act as an inspiration to future generations of mathematicians to tackle a job that will never be complete. Erweiterte Suche. Springer Professional. Inhaltsverzeichnis Frontmatter 1. Introduction Abstract. However, [ ] also contains several unpublished manuscripts by Ramanujan, letters that Ramanujan wrote to G.

It has been our goal to cover all of this material.

## Oh no, there's been an error

Without Abstract. We repeat them here in standard notation. Because Ramanujan used the same notation for each of the two sets of five functions, to avoid ambiguity and to be consistent with the notation introduced by Watson [ ], we have appended the subscript 0 to those members of the first family, and the subscript 1 to those members of the second family. Partial fractions arise again and again in the Lost Notebook.

Indeed, we have already seen instances of partial fractions e. On pages 2 and 17 in his Lost Notebook [ ], Ramanujan recorded four identities involving the rank generating function. Of course, Ramanujan would not have used this terminology, because the rank of a partition was not defined until by F. Dyson [ ]. He defined the rank of a partition to be the largest part minus the number of parts.

This chapter and the next are devoted to the proofs of ten identities from the Lost Notebook. We place them, five each, in the following two entries. The remainder of this chapter is devoted to proving that the assertions in each entry are equivalent, i.

The following chapter is devoted to proving that the fifth identity in each entry is true. In Chapter 3, Section 3. The point of the latter chapter was to reveal that the conjectures could be separated into two groups of 5 each and that the conjectures within each group are equivalent.

Unlike the fifth order mock theta functions, the sixth order mock theta functions so named in [ 39 ] seemingly do not yield to any elementary considerations. Consequently, this chapter will, of necessity, be somewhat long in order to include not only analogues of the mock theta conjectures cf. Chapter 6 , but also the various relations between these functions cf. Chapter 5.

To split this lengthy chapter into manageable pieces, we proceed as follows. Section 8. In Section 8. The previous chapter provided an account of S.
