By variational methods, for a kind of Yamabe problem whose scalar curvature vanishes in the unit ball BN and on the boundary SN-1 the mean curvature is prescribed, we construct multi-peak solutions whose maxima are located on the boundary as the parameter tends to 0+ under certain assumptions. We also obtain the asymptotic behaviors of the solutions. © 2008 Institute of Applied Mathematics, Academy of Mathematics and System Sciences, Chi...
