 19h comment Any closed form for series like $F(x)=\Sigma_{i=p}^{\infty}x^p$,p is prime$?XL, if the answer is helpful, even if it's not a complete answer, I'd encourage you to vote it up. 19h comment Any closed form for series like$F(x)=\Sigma_{i=p}^{\infty}x^p$,p is prime$?XL, you came back here to edit your question, but did nothing to engage with the comments. Why? 22h comment Weiestrass Form You've returned to edit the question --- have you anything to say about Allan's answer? 22h comment finding an integer that minimizes a functionSeems there's no research angle here, making this question off-topic for this website. 22h revised Anything special (historical?) about surface $x\cdot y\cdot z\ +\ x+y+z=0$?edited title 22h comment Any closed form for series like $F(x)=\Sigma_{i=p}^{\infty}x^p$,p is prime$?Your first display makes no sense. Maybe you meant $$\sum_{p=2}^{\infty}x^p,p{\rm\ is\ prime}$$ 22h comment Given an even integer N, what is the minimum set of primes such that any even number x <= N can be expressed as the sum of two primes from the set?I'm looking at the review of Granville's paper at MR, and it looks like where you have$c\sqrt x\log x$it should be$c\sqrt{x\log x}$. May21 comment Can group solvability be detected from identities among the generators?Write$a=(12)$,$b=(1234)$. Then$X_1$just has the two elements$a^{-1}b^{-1}ab$and$b^{-1}a^{-1}ba$(and the identity), right? And I think these come to$(132)$and$(123)$, respectively. May21 answered Can group solvability be detected from identities among the generators? May17 comment how to calculate probability that straight line is covered by sensors with radius r"perimeter of straight line"? Is that any different from "straight line"? or are you asking about the perimeter of a polygonal region in the plane? "random size"? random, according to which distribution? "small n circles"? What does this mean? How small is small? This question needs a lot of clarification before it will be possible to give an answer. May17 revised Weiestrass Form typos May17 comment Can distinct open knots correspond to the same closed knot?"There's an obvious function mapping from open knots to closed knots - just connect the two ends together." But you can do this connection in many ways, including ways that cause the open ends to pass through various loops in the knot, resulting in different closed knots. I think you have to be a little careful about how you close the knot. May15 comment A catalog of faithful representations of finite groups?Related question which might be of interest: mathoverflow.net/questions/4280/… May14 comment two boy scouts problemsKeyphrases: combinatorial designs, graeco-latin square. May14 revised Reference for original paper (but translated to English) of Matiyasevich’s proof of Fibonacci relation being Diophantine?improved formatting May8 comment Discrete disjoint covering of integer latticesI don't know what you mean by "the basis-and-origin simplex". May8 comment Is it difficult to prove that nature is chaotic?Proving that a mathematical model is (or isn't) chaotic is not quite the same thing as proving that Nature is (or isn't) chaotic. May7 answered Square and reversed integer May7 comment Square and reversed integer@ARupinski, OP alleges A implies B, you present a counterexample to B implies A. May7 comment cube + cube + cube = cubeNot that this helps much, but it appears to be JHI, not GHI. May6 comment Is rigour just a ritual that most mathematicians wish to get rid of if they could? By 2100, 10 billion dollars will be the price of a loaf of bread. May1 comment Dimension of incomplete matrix over finite fields.Rob, I have nothing resembling a proof, just a feeling I gained through thinking about small examples. Apr30 revised Concerning Fritz John’s article, The Ultrahyperbolic Differential Equation With Four Independent Variablesstopped shouting Apr30 comment Dimension of incomplete matrix over finite fields.I think the question only has a shot at an affirmative answer if$2^n$is large compared to$p$. Apr30 comment Links which HOMFLY homology distinguish but the HOMFLY polynomial does not.A related question is mathoverflow.net/questions/25747/… Apr30 comment Dimension of incomplete matrix over finite fields.${\bf Z}_{p^k}$is not a field, unless$k=1$. Apr27 comment Bost’s slopes method for Lindemann theoremCan you give us a reference for "Bost's slopes method"? Apr27 comment Hamming codes from overlapping vectorsSounds like a question about autocorrelation of a sequence. Apr17 answered What is the correspondence between combinatorial problems and the location of the zeroes of polynomials called? Apr14 comment permutation representation of$S_n$What is$K$?${}$Apr13 comment distinct odd part partitions and symmetric partitionsDoesn't seem to have a research interest, which is what this website is about. Apr9 comment Isometry on a Hamming cubecategory-theory? Must be a better tag.... Apr3 comment At what point does Miller-Rabin become faster than trial division?@Emil, how many primes in a handful? Apr2 comment A Diophantine equation involving prime powers.Greg means it forces$p$to be even. I think$2^x-3^y=1$was dealt with by Gersonides, long before Catalan. Apr1 comment Which compositions have these sum-like and product-like properties on the positive reals?$x*y=x^{\log y}$. Mar27 revised About the boundedness of the set of Mordell-Weil ranksretagged Mar27 comment bijection between number of partitions of 2n satisfying certain conditions with number of partitions of nHow do you know (or what makes you expect) this is true? Mar26 comment$\prod_{n=1}^{\infty} n{}^{\mu(n)}=\frac{1}{4 \pi ^2}$In its current state, I don't see where there's a question. Mar18 answered Books request on nonlinear recurrence relations.
