Difference sets in $R^{d}$

David Conlon, Jeck Lim

Let $d \geq 2$ be a natural number. We show that $∣ A - A ∣ \geq (2 d - 2 + \frac{1}{d - 1}) ∣ A ∣ - (2 d^{2} - 4 d + 3)$ for any sufficiently large finite subset $A$ of $R^{d}$ that…

Fixing a hole

David Conlon, Jeck Lim

We show that any finite $S \subset R^{d}$ in general position has arbitrarily large supersets $T \supseteq S$ in general position with the property that $T$ contains no empt…
