Abstract
AbstractThis paper is devoted to the study of anisotropic parabolic equation related to the $p_{i}$
p
i
-Laplacian with a source term $f(u)$
f
(
u
)
. If $f(u)=0$
f
(
u
)
=
0
, then the fundamental solution of the equation is constructed. If there are some restrictions on the growth order of u in the source term, the initial energy $E(0)$
E
(
0
)
is positive and has a super boundedness, which depends on the Sobolev imbedding index, then the local solution may blow up in finite time.
