Abstract
We determine all real meromorphic functions f in the plane such that f′ has finitely many zeros the poles of f have bounded multiplicities and f and F have finitely many nonreal zeros where F is a linear differential polynomial given by F = f k+Σ j=0 k−1 α j f j in which k ⩾ 2 and the coefficients a j are real numbers with a 0 ≠ 0
