Nov 23, 2011 at 7:39 comment added Pietro Majer Thank you. It remains a problem: conversely, is the set $C$ nowhere dense? We may also state the problem in a slightly general form: suppose $A(t)$, for $0\le t \le 1$, is a family of convex sets, with $A(t)\subset A(s)$ for $t\le s$, and $A(0)$={0} and $A(1)$= the unit ball. Suppose $f$ is a selection curve of $\partial A$: for all $t$, $f(t)\in\partial A(t)$. Can one have $f([0,1])=A(1)$ ?

Nov 4, 2011 at 2:43 comment added Michael Hardy Tonight I'm nowhere near a printer. I'll print this tomorrow so I can look it over while making marginal notes as that becomes convenient and then see if I have any comments or questions. Maybe the hard part is proving that the set in question is always nowhere dense.
