 Sep 5 awarded Popular Question Jul 29 answered Counting elements with certain word length in abelian groups Jul 12 revised Nonstandard analysis in probability theory grammar fix Jun 7 comment When is $(-1+\sqrt[3]{2})^n$ of the form $a+b\sqrt[3]{2}$? The sequence of coefficients is in the encyclopedia, though not with this context. oeis.org/A108369 May 25 revised Cohen and Selfridge's proof about odd numbers which are neither the sum nor difference of a power of two and a prime edited tags; edited title May 24 comment Prescribed values for the uniform density @SalvoTringali : It's often difficult to put a finger on what is a nonsequitor and what is simply my obtuseness. The result is true, but I haven't been able to understand Misik's proof in a detailed way. In "On asymptotic and logarithmic densities" (2005), Luca and Porubsky prove just the 4-densities result in 12 pages, while Misik proves much more in only 8 pages.

This is the Irwin-Hall distribution; there are indeed formulas in Wikipedia. Nov 28 comment What's the volume of $\{x\in[0,1]^n|\sum x_i\le t\}$ for real $t$? This is the Irwin-Hall distribution. Nov 19 comment Dynamics in the integers - Floor function The sequence $[n\alpha]$ is known as a Beatty sequence; the indicator function of a Beatty sequence (with irrational $\alpha$) is known as a Sturmian word. There are hundreds of papers working out properties of Beatty sequences. Nov 16 comment Rate of convergence of an irrational rotation Ah, I see. But still a little weird as distance isn't respected by the isomorphism (but boundedly so), and certainly algebraic $\alpha$ is not the same as algebraic $\lambda$ (but that wasn't part of the original question). Nov 15 comment Rate of convergence of an irrational rotation This answer has been accepted and all, but isn't it completely different from the original question? Here, powers of $\lambda$; there, multiples of $\alpha$.
