UNSOLVED PROBLEMS. Edited by O. Strauch Also it welcomes open problems in the line of the aim of this UDT for possible . Ramanujan function. In mathematics, in the field of number theory, the Ramanujan–Nagell equation is an equation Triangular Mersenne numbers[edit]. The problem of finding all numbers of the form 2b − 1 (Mersenne numbers) which are triangular is equivalent. 1 May History of mathematician Srinivasa Ramanujan’s lost notebooks and an exploration of solutions to One of Ramanujan’s unsolved equations.

All he had was a pen and pad of paper no Mathematica at that timeand he ramanujan unsolved problems to write down his equations before he died. Asymptotic Expansions in the Wolfram Language July 19, ramanujan unsolved problems The problem stems from Ramanujan’s work on modular equations of degree In mathematicsin the field of number theorythe Ramanujan—Nagell equation is an equation between a square number and a number that is seven less than a power of ramajujan.

Or continue as a guest your comment will be held for moderation:. And the method can easily be generalized to find many more, so far unknown, values for S qand similarly for R q.

First, calculate a numerical value for the point of interest. By using this site, you agree to the Terms of Use and Privacy Policy. A tout seigneur ramanujan unsolved problems honneur!

Clearing ramanujan unsolved problems, we obtain the above form of the result. Why were the problems ramanujan unsolved problems exactly? The values agree to at least places. Wolfram Science Technology-enabling science of the computational universe.

It is named after Srinivasa Ramanujanwho conjectured that it has only five integer solutions, and after Trygve Nagellwho proved the conjecture.

Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site the association bonus does not count. We do not record the value here, because it is not particularly elegant. Is’nt this the approach of Wu to solve geometric problems by mechanical methods? This survey is available from Bruce Berndt website: Here are pictures ramanujan unsolved problems the behavior of the R function on the unit disk in the complex plane.

All of these are readily solved with Mathematica. Getting to the Point: Transform everything in algebraic equations, eg. I just cannot resist posting it here! So how did Ramanujan come up with such a problem? An elementary solution to the specific geometric problem you’ve mentioned can be found in Ramanujan unsolved problems Notebooks, Part III by Berndt Springer,pp. He wrote the following incomplete equation with 14 others, only 3 of them solved. The functions R and Ramanujan unsolved problems are two of the few named functions devoted to continued fractions.

Would ramanujan unsolved problems like to ramanujan unsolved problems one of these unanswered questions instead? More formal definitions are as follows:.


He claimed to have solutions for a particular function, but only had time to write down a few before moving on to other areas of mathematics.

Since problms of these are algebraic numbers with elegant representations, this is a rather convincing check.

Ramanujan–Nagell equation – Wikipedia

He surely wouldn’t have discovered this problem by the algebraic technique you have given. This is the modular equation of order 5 for S: Several of the problems are elementary and can be attacked with a background of only high school mathematics. Second, conjecture a closed algebraic form for this number. Big O and Friends: In the Wikipedia page on Ramanujan, there is a link ramanujan unsolved problems a collection of problems posed by him. Enable JavaScript to interact ramanujan unsolved problems content and submit ramanujan unsolved problems on Wolfram websites.

A result of Siegel implies that the number of solutions in each case is finite. So, Are all these problems solved? Oh well, he sure can make us rack our brains out. MathOverflow works best with JavaScript enabled.
