Abstract
The Cauchy problem of the following equation
is considered, where ,
,
,
and
. We are initially interested in the problem of finding sharp conditions ensuring the local existence of solutions, and give the proof of the local existence of solutions. Then our attention is focus on the global existence and nonexistence of solutions. In particular, a Fujita’s type critical exponent is obtained. These extend several classical conditions and results to the problem considered here.
