Abstract: We study the asymptotic behavior of least energy solutions to the equation Δ2u=c0K(x)upε with the Navier boundary condition as ε→+0, where Ω is a smooth bounded domain in RN (N≥5), c0=(N−4)(N−2)N(N+2) and pε=(N+4)/(N−4)−ε, ε>0. Under some assumptions on the coefficient function K, we obtain fairly precise asymptotics of the L∞-norm of least energy solutions.
