R. Bamon et al., ON CENTRAL CANTOR SETS WITH SELF-ARITHMETIC DIFFERENCE OF POSITIVE LEBESGUE MEASURE, Journal of the London Mathematical Society, 52, 1995, pp. 137-146
We prove the existence of C-r- (but not C-r+1-) regular central Canter
sets with zero Lebesgue measure such that their self arithmetic diffe
rence is a Canter set with positive Lebesgue measure. This is motivate
d by a conjecture in the field of bifurcations of dynamical systems po
sed by Jacob Palis.
