We study the semilinear equation( − Δ ) s u + ( 1 + ϵV ( x ) ) u = u p ,u > 0inR N ,where 0 < s < 1, 1 < p < N + 2 s N − 2 s , V ( x ) is a sufficiently smooth non‐symmetric potential with V ( x ) ∈ L ∞ ( R N ) , and ϵ > 0 is a small number. Letting U be the radial ground state of (−Δ) s U + U − U p =0 inR N , we build solutions of the formu ( x ) ∼ ∑ j = 1 m U ( x − ϑ j )for points ϑ j , j = 1,⋯, m , using a Lyapunov–Schmidt variational reduction.
