Abstract: | We study the existence of a nonnegative generalized solution of an initial-boundary value problem for the heat equation with a singular potential in an arbitrary bounded domain Ω ? R n , n ≥ 3, containing the unit ball. We show that if the condition ∝ Ω V n/2+s |x| s dx ≤ c n is satisfied for some s ≥ 0 and c n = c n (n, s, Ω) > 0, then the problem in question has a nonnegative solution. |
