Abstract: Of interest in this talk is the asymptotic behavior of non-negative, radial solutions to the fourth-order critical Hardy-Hénon equation with the weight |x|^σ. In an earlier work published in Rend. Lincei Mat. Appl., R.L. Frank and T. König (2019) showed that solutions must decay fast as that of the fundamental solution of the biLaplace equation. Previously, this result was known when σ=0 as a consequence of the classification results obtained by C.S. Lin in Comment. Math. Helv. and by X. Xu in Proc. Roy. Soc. Edinburgh Sect. A. In this talk, I present the same result for any σ>0. Our key ingredient is the Fazly-Wei-Xu pointwise inequality. To the best of our knowledge, this is the first direct application of this intriguing inequality.
