### If $F(x,\bullet) \in {L^{2}}(G,B)$ for all $x \in G$, then is $x \mapsto F(x,\bullet)$ strongly measurable?
This question is related to something that I asked yesterday: If $F(x,\bullet) \in {L^{\infty}}(G,B)$ for all $x \in G$, then is $x \mapsto F(x,\bullet)$ strongly measurable? Pietro Majer ...
Let A be a set of $2m$ points on the plane so that no open set of diameter $2$ has more than m of them. Define $A+A+...+A$ ($k$ times) to be the multiset of $k$-sums from $A$. That is, we consider all ...
