We study the existence of nonnegative solutions of a parabolic problem \( \frac{\partial u}{\partial t}=-{\left(-\Delta \right)}^{\frac{\alpha }{2}}u+\frac{c}{{\left|x\right|}^{\alpha }}u \) in ℝd × (0, T). Here, 0 < α < min(2, d), \( {\left(-\Delta \right)}^{\frac{\alpha }{2}} \) is the fractional Laplacian on ℝd and u0 ∈ L2(ℝd).
