This paper deals with the formation of singularities of rough blow-up solutions to the fourth-order nonlinear Schrödinger equation. The limiting profile and L 2 -concentration of the rough blow-up solutions are obtained in H s ( R 4 ) with s > s 0 , where s 0 ≤ 9 + 721 20 ≈ 1.793 . The new ingred...
