Abstract
We continue to study the asymptotic behavior of least energy solutions to the following fourth order elliptic problem E p E p left beginarrayll Delta2 u = up hboxin Omega u 0 hboxin Omega u partialOmega = Delta u partialOmega = 0 endarray right as p gets large where Ω is a smooth bounded domain in R 4 In our earlier paper Takahashi in Osaka J Math 2006 we have shown that the least energy solutions remain bounded uniformly in p and they have one or two “peaks” away form the boundary In this note following the arguments in Adimurthi and Grossi Proc AMS 13241013–1019 2003 and Lin and Wei Comm Pure Appl Math 56784–809 2003 we will obtain more sharper estimates of the upper bound of the least energy solutions and prove that the least energy solutions must develop singlepoint spiky pattern under the assumption that the domain is convex
