Abstract:
We shall present the critical exponent
for the Cauchy problem
where
,
and
;
that is, the small data global
existence of solutions can be derived to the problem above if
.
Furthermore, in the case of
the non-existence of global
solution can be obtained with the initial data having positive average value.
