• meromorphic function
• value distribution
• normal families

Let F be a family of functions meromorphic in a domain D, let n >= 2 be a positive integer, and let a not equal 0, b be two finite complex numbers. If, for each f is an element of F, all of whose zeros have multiplicity at least k + 1, and f + a(f((k)))(n) not equal b in D, then F is normal in D.
