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

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 4densities result in 12 pages, while Misik proves much more in only 8 pages.

Nimber multiplication
This is discussed at length in Lenstra's "Nim multiplication". openaccess.leidenuniv.nl/bitstream/handle/1887/2125/346_027.pdf

What's the volume of $\{x\in[0,1]^n\sum x_i\le t\}$ for real $t$?
This is the IrwinHall distribution; there are indeed formulas in Wikipedia.

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.

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).

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 $\alpha$.
