Abstract: | We consider the equivalence between the fractional partial differential equation (P) with Hardy term in Rn : (- Δ) α2 u(x) = 1xγup (x) x ∈ Rn ,and the correspondingintegral equation u(x)=U(x) ≥ 0 x ∈ Rn c∫up (y)| x - y | n-α | y |γdy ,where 0 〈 γ〈 α〈 2 #n and c is a constant .A new and direct approach is Rn employed to prove the equivalence . Once the equivalence is established ,all results of the positive solutions to an integral equation can be applied to the fractional partical difference equation (PDE) . |
