Let for
gif.latex


and
gif.latex
. Assume that

Prove:

a. If
gif.latex
with
gif.latex
and
gif.latex
are solutions of
gif.latex

with
gif.latex
then
gif.latex
for
gif.latex


b. Assume (for simplicity) that
gif.latex
is continuously differentiable. If
gif.latex
has a nonextendable solution
gif.latex
with
gif.latex
then the domain of every nonextendable solution
gif.latex
of
gif.latex
with
gif.latex
contains
gif.latex
.
