| Mar 31, 2018 at 14:39 | comment | added | Paolo Leonetti | @MartinSleziak You are right in one point: I didn't check translations and the result depends on the choice of the bijection. On the other hand, I was referring the finite analogue, hence we'd need only $X \cap Y+k$ finite for each $k$. I don't know whether this can be fixed | |
| Mar 31, 2018 at 14:34 | comment | added | Martin Sleziak | When you mention the construction of almost disjoint family from Albiac-Kalton, you mean that for any two sets from this family you have that $X\cap Y+k$ has zero density, right? Whether or not all these sets have positive upper density probably depends on the choice of the sequences and the choice of the bijection between $\mathbf N$ and $\mathbf Q$. | |
