In the spring of 1976, George Andrews of Pennsylvania nation college visited the library at Trinity collage, Cambridge, to ascertain the papers of the past due G.N. Watson. between those papers, Andrews stumbled on a sheaf of 138 pages within the handwriting of Srinivasa Ramanujan. This manuscript was once quickly particular, "Ramanujan's misplaced notebook." Its discovery has often been deemed the mathematical similar of discovering Beethoven's 10th symphony.

This quantity is the fourth of five volumes that the authors plan to jot down on Ramanujan’s misplaced notebook. In distinction to the first 3 books on Ramanujan's misplaced computer, the fourth ebook doesn't specialise in q-series. many of the entries tested during this quantity fall lower than the purviews of quantity concept and classical analysis. a number of incomplete manuscripts of Ramanujan released by means of Narosa with the misplaced computer are discussed. 3 of the partial manuscripts are on diophantine approximation, and others are in classical Fourier research and top quantity theory. many of the entries in quantity idea fall below the umbrella of classical analytic quantity theory. might be the main exciting entries are attached with the classical, unsolved circle and divisor problems.

Review from the second one volume:

"Fans of Ramanujan's arithmetic are guaranteed to be extremely joyful via this booklet. whereas a few of the content material is taken at once from released papers, so much chapters include new fabric and a few formerly released proofs were greater. Many entries are only begging for extra learn and may surely be inspiring learn for many years to return. the following installment during this sequence is eagerly awaited."

Review from the 1st volume:

"Andrews and Berndt are to be congratulated at the activity they're doing. this is often the 1st step...on how one can an knowing of the paintings of the genius Ramanujan. it may act as an suggestion to destiny generations of mathematicians to take on a role that may by no means be complete."
