In this paper we consider the Cauchy problem for the singular semilinear parabolic equation u t-Δu+V 1(x)u=V 2(x)u p,x∈R n\{0},t>0, where V 1(x),V 2(x) may have singularities at the origin.

Using functions of the Kato class and the Green tight functions we got the existence of the positive solution being singular at the origin.展开更多
