Abstract. We show a class of homogeneous polynomials of FermatWaring type such that for a polynomial P of this class, if P (f 1 , . . . , f N+1 ) = P (g 1 , . . . , g N+1 ), where f 1 , . . . , f N+1 ; g 1 , . . . , g N+1 are two families of linearly independent entire functions, then f i = cg i , i = 1, 2, . . . , N + 1, where c is a root of unity. As a consequence, we prove that if X is a hypersurface defined by a homogeneous polynomial in this class, then X is a unique range set for linearly non-degenerate non-Archimedean holomorphic curves.
