Abstract

In this paper, we consider the inequality estimates of the positive solutions for the inhomogeneous biharmonic equation $$-\Delta^{2} u+u^{p}+f(x)=0 \; \rm{in} \; \mathbb{R}^{n},$$ − Δ 2 u + u p + f ( x ) = 0 i n R n , where Δ2 is the biharmonic operator, p > 1, n ≥ 5 and 0 ≢ f ∈ C(ℝ n ) is a given nonnegative function. We obtain different inequality estimates of Eq.(*), with which the necessary conditions of existence on f and p are also established.
