We estimate the Hausdorff
measure and dimension of Cantor sets in terms of a sequence given by the lengths of
the bounded complementary intervals. The results provide the relation between
the decay rate of this sequence and the dimension of the associated Cantor
set.
It is well-known that not every Cantor set on the line is an s-set for
some 0 ≤ s ≤ 1. However, if the sequence associated to the Cantor set C is
nonincreasing, we show that C is an h-set for some continuous, concave dimension
function h. We construct the function h from the sequence associated to the set
C.
