Abstract:A.V. Lair and A. W. Wood (2000) and A. V. Lair (2010) provided necessary and sufficient conditions for the existence of the entire large solutions for semilinear elliptic equation Ziu = p ( | x | ) u^α and system A u =p ( | x | ) u^β ,△v = q( | x| )v^β on R^n( n ≥3 ), where p and q are nonnegative continuous functions on R^n and 0 〈 α, β ≤ 1. We also study the necessary and sufficient conditions for the existence of the entire large solutions to them when α ,β 〈 0. Our results complete the ones when α 〈 0 ( or α ,β 〈 0) given by A. V. Lair, A. W. Wood (2000) and A. V. Lair(2010).
Keywords:semilinear elliptic equation(system)  entire large solution  existence
