Existence of infinitely many spike solutions for a critical Hénon type biharmonic equation

Following the idea of Wei and Yan [32], with new ingredients to take care of the critical dimension n=5n=5, we construct infinitely many solutions of the biharmonic equation Δ2v=|x|αvn+4n−4 in the unit ball of RnRn (n⩾5n⩾5, α>0α>0) with the Navier conditions v=Δv=0v=Δv=0 on the boundary.
