346[ 4a, 10 ]
Prove that every finite subset of
is a Jordan region of volume zero.
Show that even in
, part a. is not true if "finite" is replaced by "countable."
By an interval in
we mean a set of the form
for some real a, b, c. Prove that every interval in
is a Jordan region.
Suppose that V is a bounded open set of
and g:V ->
is continuously differentiable on V.
Let H be a compact subset of V. Show that there is a constant C>0 (depending only on g, H, n) so that for all cubes Q in H,
Show that if E, a subset of V has volume zero then g(E) has volume zero.
